Understanding the Lift and Shift ProcessThese topics describe the lift and shift process: “Lift and Shift Overview” on page 9“Requirements” on page 14 “Example Configuration and Prompts” on page 16 For additional lift and shift guides, visit the Oracle Solaris on SPARC - Lift and ShiftDocumentation Library at https://docs.oracle.com/cd/E94980 01/Lift and Shift OverviewThis document provides instructions for performing a physical to virtual lift and shift. Thetechniques in this document are specifically aimed at migrating workloads running on OracleSolaris 10 with ZFS root file systems on SPARC systems to Oracle Solaris 10 Guest Domainsin Oracle Solaris 11.3 (or later) running on more modern sun4v hardware.Understanding the Lift and Shift Process9
Lift and Shift OverviewScopeThe instructions in this document are limited to the lift and shift of an Oracle Solaris 10environment with ZFS root file systems to an Oracle Solaris 11 Environment that is configuredwith an Oracle Solaris 10 guest domain. The source Oracle Solaris 10 environment can beconfigured with Solaris zones. In such cases, such as the example in this document, the globalzone, non-global zones, and associated applications and data are migrated to the target system.It is also possible to use this guide to migrate a non-virtualized Oracle Solaris 10 environment,as long as the environment is based on ZFS root file systems.This procedure does not take down the source machine during the archive creation, thereforethe source system is available for use. However, to maintain the integrity of the application(Oracle Database and Apache web server in this case), it is a best practice to cleanly shutdownthe services.The performance measurement of the source and target system is not within the scope of thisdocument.10Lift and Shift Guide - Migrating Workloads from Oracle Solaris 10 (ZFS) SPARC Systems to Oracle Solaris 10 GuestDomains February 2020
Lift and Shift OverviewLift and Shift ProcessThe lift and shift process involves using a variety of Oracle Solaris utilities to migrate the entiresource configuration, including all associated applications and data, to an Oracle Solaris 10guest domain on the target system. To accomplish this migration, the following activities areperformed, although not necessarily in this exact order. The procedures in subsequent chaptersorder the activities to minimize the amount of time that services are unavailable. Identify and resolve all source system issues – (Not covered in this guide) Resolvingissues before migration simplifies troubleshooting by eliminating the migration as a possiblecause of issues. Consider checking log files for issues and applying the latest critical pathupdates (see Critical Patch Update Bulletins). In some cases, rebooting a system that hasn'tbeen rebooted in a long time can reveal issues.Assess the source system – Determine the amount of resources used to support theworkloads. Gain an understanding of the configuration so that you can replicate theconfiguration on the target system. Collect information about the CPU, memory, storage,and workload resources.Select the target system – Select a target system that has sufficient, or additional resourcesto support the workloads. The target system is usually a more modern system that providessecurity and performance improvements, and possible cost savings such as lower power,cooling, and support costs.Prepare the source system – Patches, which provide the necessary lift and shift utilities,are installed on the source system.Prepare the target system – CPU, memory, and storage resources are configured toaccommodate the incoming Oracle Solaris 10 environment.Prepare shared storage – Shared storage is used to capture the source workloads and thenused to restore the workloads on the target system. Using shared storage is central to thislift-and-shift scenario. Storage on the target system is exported as a network file system andmounted on the source system, providing easy access to common storage from the source ortarget system.Create an Oracle Solaris 10 guest domain on the target system – A new Oracle Solaris10 guest domain is created on the target system using an Oracle provided OVM template.The guest domain will host the incoming Oracle Solaris 10 environment. The followingillustration shows the commands that are used to prepare the guest domain.Understanding the Lift and Shift Process11
Lift and Shift Overview12 Lift – The ldmp2vz collect command is used to capture the source system's OS ZFSfile system, and capture the source's zone configuration (if present) into a flash archive(FLAR). Then, using various utilities, all zones, along with their associated storage content,applications, and application data are lifted from the source and copied to the sharedstorage. Shift – The ldmp2vz convert command uses the FLAR that is on the shared storage torestore the source system's OS ZFS file systems to the target guest domain in a new bootenvironment. The zone configuration and storage is also restored. If the zone storage isincluded in the root file systems, then that storage is also restored.Lift and Shift Guide - Migrating Workloads from Oracle Solaris 10 (ZFS) SPARC Systems to Oracle Solaris 10 GuestDomains February 2020
Lift and Shift Overview Transfer Applications and Data – Different utilities are used to transfer workloadcomponents based on the type of file system where the component resides. In some cases,the output of one command is piped to pigz or gunzip to improve efficiency throughcompression and decompression that those commands provide. This diagram shows thedifferent utilities.Understanding the Lift and Shift Process13
Requirements Reconfigure – The shifted environment requires post-migration reconfiguration to functionin the new environment. For example, the network configuration is carried over from thesource environment, and usually needs to be changed to function in the new environment. Ifprocessor sets were used in the source environment, they might need some adjustment whenthey are restored in the target environment.RequirementsThe lift and shift process described in this document has the following requirements, andincludes instructions for satisfying them:Source System Installation of the following patches on the source system (covered in “Prepare the SourceSystem” on page 46): The SUNWldm package – Oracle VM Server for SPARC 3.2. The SUNWldmp2v package – Oracle VM Server for SPARC 3.2.Patch 119534-33 (or later) – Flash archive patch. 14Lift and Shift Guide - Migrating Workloads from Oracle Solaris 10 (ZFS) SPARC Systems to Oracle Solaris 10 GuestDomains February 2020
Requirements Patch 151934-06 (or later) – VM Server for SPARC 3.2 ldmd patch, provides lift andshift utilities such as ldmp2vz collect, ldmp2vz convert, and pigz.Target System The target control domain must be running Oracle Solaris 11.3 SRU 35 (or later) andLDOM 3.5.0.3.3 (or later).Installation of the following patches in the target guest domain (covered in “Patch the TargetGuest Domain” on page 43): The latest available Oracle Solaris 10 Recommended patch set(10 Recommended CPU 2018-01 at minimum). The patch set provides proactive patchingand ensures that the commands in this document run as expected. For more informationrefer to Critical Patch Updates and MOS knowledge Doc ID 1272947.1 from My OracleSupport (https://support.oracle.com).Note - This document uses the 10 Recommended CPU 2018-10 version of this patchset. The SUNWldm package – Oracle VM Server for SPARC 3.2.The SUNWldmp2v package – Oracle VM Server for SPARC 3.2. Patch 119534-33 (or later) – Flash archive patch. Patch 151934-06 (or later) – VM Server for SPARC 3.2 ldmd patch, provides lift andshift utilities such as ldmp2vz collect, ldmp2vz convert, and pigz.Plan to download the Oracle VM Template for Oracle VM Server with Oracle Solaris10.1/13 (Solaris10 OVA) to the target system (covered in “Create a Target GuestDomain” on page 39). Shared Storage On the shared storage, ensure that there is sufficient storage space to temporarily store theimage of the source system that is used to perform the lift and shift. The storage must beaccessible to the source and target systems. For space requirements and instructions, see“Prepare the Shared Storage” on page 35. Plan to download the Oracle Solaris10 (SPARC) ISO (sol-10-u11-ga-sparc-dvd.iso) toshared storage (covered in “Prepare the Shared Storage” on page 35).Plan to download and unzip all required patches to shared storage (covered in “Prepare theShared Storage” on page 35). This enables you to download the patches in one location,and patch the source and target systems from that single location. Understanding the Lift and Shift Process15
Example Configuration and PromptsExample Configuration and PromptsThe lift and shift process in this document is based on a real in-house lift and shift activity. Theexamples provided in this document are excerpts from that activity. Command line promptsidentify on which system the commands are performed.These systems are used in the examples: Source system – A SPARC Enterprise M9000 (sun4u) system running the Oracle Solaris 10OS with two non-global zones: dbzone – Running Oracle Database 12.1.0.2 webzone – Running Apache web server on a Solaris sparse root zone (zone storage is inthe root file system)Target system – A SPARC S7-2 (sun4v) system, running the Oracle Solaris 11 OS. Duringthe lift and shift procedures, this system is prepared with an Oracle Solaris 10 guest domainthat will host the source OS and workloads (the database on the dbzone zone and Apacheweb server on the webzone zone).The following diagrams show the source system configuration and the lift and shift processused in the examples in this guide.16Lift and Shift Guide - Migrating Workloads from Oracle Solaris 10 (ZFS) SPARC Systems to Oracle Solaris 10 GuestDomains February 2020

Preparing the Lift and Shift SystemsThese topics describe how to prepare the source system, the target system, and the sharedstorage for the lift and shift process: “Review the Source System Configuration” on page 21“Prepare the Target System” on page 29“Prepare the Shared Storage” on page 35“Create a Target Guest Domain” on page 39“Patch the Target Guest Domain” on page 43“Prepare the Source System” on page 46Review the Source System ConfigurationThe steps and examples in this section provide commands you can use to determine theconfiguration of your source system, including details about the zones that you plan to lift andshift. After the lift and shift process, the configuration information can also serve as a referencewhen you verify the migrated zones on the target system.As you perform this procedure, take into account the state of your source system and adjust andomit steps as needed.1.(Optional) On the source system, start a process that captures the output that iscollected in this task.Capturing the commands and output provides a means to refer back to the data that is collected.There are a variety of methods to capture output. You can run the script(1M) command to makea record of a terminal session, or use a terminal window with command and output collectioncapabilities.Example:[email protected]# script /tmp/source zones output.txtNote – When you want to stop capturing output, type Ctr-D.Preparing the Lift and Shift Systems21
