By importing configuration and, optionally, data, this version of vRealize Operations Manager can assume the monitoring of an earlier vCenter Operations Manager deployment.

Migration occurs side by side and does not turn off the source. After migration, both target and source can monitor the same objects. When you turn off the earlier deployment, monitoring of the inventory and data is done solely by the new version of vRealize Operations Manager. Performing the entire process is known as a migration-based upgrade.

A vRealize Operations Manager migration requires that you deploy and configure a target cluster of new nodes in the same way as you would for a new vRealize Operations Manager installation. Then, you perform a one-time connection to your previous vCenter Operations Manager source deployment to import the configuration and, optionally, data from that environment.
