12.3 Upgrades
An upgrade to vRealize Operations Manager 6.x from vCenter Operations Manager 5.8 is done by setting up a new vRealize Operations Manager 6.x environment and importing the previous version’s configuration and data.
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.
The high-level steps to perform a migration-based upgrade are:
• Deploy and configure a target cluster of new nodes (the same way as for a new vRealize Operations Manager installation).
• Perform a one-time connection to the previous vCenter Operations Manager source deployment to import the configuration and, optionally, data from that environment.
• Run both vRealize Operations Manager 6.x and vCenter Operations Manager side by side until the legacy environment can be shut down.
Refer to the product documentation for the detailed upgrade process.
