You must upgrade the components in your vSphere and Site Recovery Manager environment in the correct order.

You must upgrade certain components of your vSphere environment before you upgrade Site Recovery Manager. You must upgrade Site Recovery Manager Server before you upgrade other Site Recovery Manager components and vSphere Replication.

Upgrade the components on the protected site before you upgrade the components on the recovery site. Upgrading the protected site first allows you to perform a disaster recovery on the recovery site if you encounter problems during the upgrade that render the protected site unusable. The exception is the ESXi hosts, which you can upgrade after you finish upgrading the other components on the protected and recovery sites.

Important:

If you configured bidirectional protection, in which each site acts as the recovery site for the virtual machines on the other site, upgrade the most critical of the sites first.

  1. Upgrade vCenter Server on the protected site.

  2. Upgrade Site Recovery Manager Server on the protected site.

  3. Upgrade the storage replication adapters (SRA) on the protected site.

  4. Upgrade the vSphere Replication appliance on the protected site.

  5. Upgrade any additional vSphere Replication server instances on the protected site.

  6. Upgrade vCenter Server on the recovery site.

  7. Upgrade Site Recovery Manager Server on the recovery site.

  8. Upgrade the storage replication adapters (SRA) on the recovery site.

  9. Upgrade the vSphere Replication appliance on the recovery site.

  10. Upgrade any additional vSphere Replication server instances on the recovery site.

  11. Configure the connection between the Site Recovery Manager sites and vSphere Replication appliances.

  12. Verify that your protection groups and recovery plans are still valid.

  13. Upgrade ESXi Server on the recovery site.

  14. Upgrade ESXi Server on the protected site.

  15. Upgrade the virtual hardware and VMware Tools on the virtual machines on the ESXi hosts.
