Before you proceed with upgrade you must increase hardware resources for each vRealize Automation appliance.

If you have taken snapshots of your vRealize Automation appliances, you must clone your appliances and increase the hardware resources on the clones. Ensure that you have at least 60 GB of free space for each appliance in your vCenter. After you clone your appliances, power down the original appliances before you perform this procedure.

These steps are based on the Windows client.


  1. Log in to vCenter Server.
  2. Select the vRealize Automation appliance and click Edit Settings.
  3. Select Memory and set the value to 18 GB.
  4. Select CPU and set the Number of virtual sockets value to 4.
  5. Extend the size of Disk 1 to 50 GB.
    1. Select Disk 1.
    2. Change the size to 50 GB.
    3. Click OK.
  6. If there is an existing virtual Disk 4 from a previous vRealize Automation 6.2.x release, delete it and add a new virtual disk.
    1. Delete Disk 4 on the cloned machine and create Disk 4 with 50 GB disk size.
    2. If you have two disks, add Disk 3 with 25 GB disk size first and then Disk 4 with 50 GB disk size.
  7. Click Add above the Resources table to add a virtual disk.
  8. Select Hard Disk for the Device Type.
  9. Click Next.
  10. Select Create a new virtual disk.
  11. Select Thin Provision.
  12. Click Next.
  13. Set Disk Size value to 50 GB.
  14. Select Store with the virtual machine.
  15. Click Next.
  16. Verify that the Independent option is unchecked for Virtual Disk Mode choose SCSI (0:3).
  17. Click Next.

    If prompted to accept recommended settings, accept the recommended settings.

  18. Click Finish.
