The vRealize Operations Manager migration-based upgrade differs from other software upgrades in a variety of ways.

For migrations, the source is the earlier version of vCenter Operations Manager, and the target is the new, current vRealize Operations Manager version. Migration occurs side by side and does not turn off the source. After migration, the target and source can both monitor the same objects until you decide to use just one or the other.


A migration-based upgrade does not install new software on a source deployment to refresh the version that is running there.

The migration-based upgrade process uses a separate, target deployment as a receiver of imported inventory and data from the source, leaving the source to continue running its earlier software version.
