Info

This document describes the steps to migrate the NFS repository to a new NFS destination.

We will explain the migration for an environment with the following separate elements:

  • Abiquo Server

  • Abiquo RS

  • Abiquo BPM (V2V)

  • KVM hypervisor

  • ESX hypervisor

This procedure was tested on Abiquo 56.1.0.

Requirements

Requirement: Rsync

Migration steps

...

To migrate the NFS, do these steps.

  1. Synchronize the NFS from the destination NFS

    Code Block

2. Stop Abiquo Server, Abiquo RS and Abiquo BPM

  1. slash (/) at the end of the folder name, to make the copy correctly, as in the example

  2. Stop the Tomcat servers in the correct order:

       Code Block
      #> umount -l /opt/vm_repository
#> mount /opt/vm_repository
  2. If you have updated the repository for KVM hypervisors, restart abiquo-aim
     Code Block
