There are alternative strategies for the upgrade of Site Recovery Manager sites.

You can upgrade all components of one of your sites before upgrading all the components on the other site. It is best practice to upgrade the Site Recovery Manager components before the Platform Services Controller and the vCenter Server components.

An alternative strategy is to upgrade the Site Recovery Manager components on both sites before upgrading the Platform Services Controller and vCenter Server components.

You can upgrade the ESXi hosts at any time.

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.

Upgrading Site Recovery Manager by Sites

By upgrading the protected site first, you can perform a disaster recovery on the recovery site if you encounter problems during the upgrade that render the protected site unusable.

  1. If you use vSphere Replication, upgrade any additional vSphere Replication servers on the protected site.

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

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

  4. If you use array-based replication, upgrade the storage replication adapters (SRA) on the protected site.

  5. (Optional) Upgrade the Platform Services Controller and all components of vCenter Server on the protected site.

  6. (Optional) Upgrade ESXi Server on the protected site.

  7. If you use vSphere Replication, upgrade any additional vSphere Replication servers on the recovery site.

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

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

  10. If you use array-based replication, upgrade the storage replication adapters (SRA) on the recovery site.

  11. (Optional) Upgrade the Platform Services Controller and all components of vCenter Server on the recovery site.

  12. (Optional) Upgrade ESXi Server on the recovery site.

  13. Verify the connection between the Site Recovery Manager sites.

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

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

Upgrading Site Recovery Manager by Components

With this strategy, you can decide when to upgrade certain components. For example, you can delay the upgrade of the Platform Services Controller appliances and vCenter Server components or the ESXi hosts. Verify which new functionalities are available with earlier versions of vCenter Server.

  1. If you use vSphere Replication, upgrade any additional vSphere Replication servers on the protected site.

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

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

  4. If you use array-based replication, upgrade the storage replication adapters (SRA) on the protected site.

  5. If you use vSphere Replication, upgrade any additional vSphere Replication servers on the recovery site.

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

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

  8. If you use array-based replication, upgrade the storage replication adapters (SRA) on the recovery site.

  9. (Optional) Upgrade the Platform Services Controller and all components of vCenter Server on the protected site.

  10. (Optional) Upgrade the Platform Services Controller and all components of vCenter Server on the recovery site.

  11. Verify the connection between the Site Recovery Manager sites.

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

  13. (Optional) Upgrade ESXi Server on the recovery site.

  14. (Optional) Upgrade ESXi Server on the protected site.

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