Lift and Shift Guide – Migrating Application Data From Older SPARC Systems to Newer SPARC Systems

Minimize Downtime with Incremental Copies

You can take advantage of incremental copy features of certain commands to minimize the downtime associated with data migration. This method migrates the data in multiple phases:

• Phase 1 – A full copy of the source data is migrated to the target system while the source system remains in production.

• Phase 2 – The target system is configured and tested while the source system remains in production.

• Phase 3 – At the cut-over phase, an incremental copy of the source data is captured and copied to the target system.

The following Oracle Solaris commands provide options for creating full and incremental copies:

• zfs send – See:

  Example 1a – Migrate a ZFS File System (Full)

  Example 1b – Migrate a ZFS File System (Incremental)

• ufsdump – See:

  Example 2a – Migrate a UFS File System (Full)

  Example 2b – Migrate a UFS File System (Incremental)
