This guide is limited to migrate a Harbor OVA instance to a next release. All Harbor data storeage settings is not manually changed after the existing Harbor OVA deployed.

Steps to migrate Harbor OVA instances:

  1. Before migration, you need to note down these following items:

    • "Networking properties" if need to keep these settings. you can find them in "Edit Settings" -> "vApp Options"

  2. In the vSphere Web Client, Select "Shut Down Guest OS" on the existing OVA instances, then select "Edit Settings", remove the "Hard disk 2", uncheck "Delete files from datastore". All disks in the logical volume "data1_vg" should be removed if the original logic volume have been extended. Use pvscan command to check disks in logical volume "data1_vg".

    Usually, the sda is the Hard Disk1 in the "Edit Settings" pannel, and the sdb is Hard Disk2 and so on. Note down all location of disk files in logical volume "data1_vg".
