Migrating ZCM to new ZCM without a ZCC

Viewed 30 times

Summary

This article explains how to migrate ZCM (Zerto Cloud Manager) to a new ZCM without a ZCC.
 

Steps

Terminology:

  • Old ZCM – the ZCM you wish to retire
  • New ZCM – the ZCM you wish to keep

 
Follow these steps on the old ZCM:

  1. In the Old ZCM, examine the properties of the Service Profiles in use. Record the SLA metrics needed such as retention, journal thresholds, etc.

  2. In the ZORG in the Old ZCM, tick the box Custom Profile.

  3. In the existing VPGs which reference the ZORG in the Old ZCM, edit the VPG and select No Zorg under the replication settings and then.

  4. Replace the VMs’ Service Profile SLA with equivalent settings under Custom Profile. You may want to confirm using VM Settings tab in Replication, that all VMs in the VPG reflect the change.

  5. Step through the Replication, Storage, Recovery and NICs tabs to ensure that the infrastructure for recovery are still in place.

  6. Save the VPG with the updated settings and ensure the VPG maintains a steady RPO and does not enter any type of Error State.  You will see some alarms saying the VPG has configured values that are outside of what is configured in the ZORG.

  7. Repeat for all other VPGs in this ZORG and the second ZORG.

  8. Once all VPGs have been updated, then go to each ZORG tab in the Old ZCM and select vCD Cloud Resources and delete all the configured vCD Resources

  9. Delete the ZORGs in the Old ZCM

  10. Remove the ZVM site from the Old ZCM


At this point you will only perform on the New ZCM:

  1. Create matching Service Profiles that have the same details as the old Service Profiles from Old ZCM

  2. Add in the Site to the New ZCM

  3. Create a new ZORG for each customer

  4. Bind the correct vCD cloud resources

  5. Tick Custom Profiles in ZORG Settings

  6. Refresh the ZVM windows for source and target ZVMs that are part of this VPG

  7. Edit the Settings of the VPG and select the correct ZORG and the newly-created Service Profile, and ensure to update VM Settings such that each VM in the VPG is updated to use the newly-created Service Profile. Also examine each of the Replication, Storage, Recovery and NICs tabs to ensure the VPG’s infrastructure resources are consistent with what values they’ve always had

  8. The VPG should be now update to Protecting status with no alarms

  9. Repeat for the other VPGs
