Introduction

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

...

This procedure was tested on Abiquo 6.1.0.

RequirementsRequirement: Rsync

Migration steps

To migrate the NFS, do these steps steps.

1. Synchronize the NFS from the destination NFS

   Code Block
   #> mount -t nfs ORIGIN_IP:/opt/vm_repository /mnt #> mkdir /opt/vm_repository #> rsync -avvv /mnt/ /opt/vm_repository/

    Be careful to put the 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:

   1. Abiquo Server

   2. Abiquo Remote Services

   3. Abiquo BPM (V2V)

3. Synchronize the NFS from the destination NFS again. Here we repeat the synchronization in case there are any changes

4. Get the current value for the repository and datacenter

   Code Block

   mysql> select * from repository; +--------------+--------------+--------------------+---------------------------------+-----------+ | idRepository | idDataCenter | name | URL | version_c | +--------------+--------------+--------------------+---------------------------------+-----------+ | 1 | 1 | virtual image repo | 10.60.13.25:/opt/vm_repository | 0 | +--------------+--------------+--------------------+---------------------------------+-----------+ 1 row in set (0.00 sec)

5. Update the database with the correct value for the new repository

   Code Block
   mysql> update repository set URL = "<NEW_IP>:/opt/vm_repository" where idDatacenter = <YOUR_DATACENTER_ID>;

6. On Abiquo Remote Services, Abiquo V2V (BPM), and all KVM hypervisors, update the mount point

   1. Edit the /etc/fstab files. Change the old IP to the NEW_IP. Save the file

      Code Block
      ** Change: ** 10.60.13.25:/opt/vm_repository /opt/vm_repository nfs defaults 0 0 ** To: ** <NEW_IP>:/opt/vm_repository /opt/vm_repository nfs defaults 0 0

      Unmount and remount the repository

      Code Block
      #> umount -l /opt/vm_repository #> mount /opt/vm_repository

7. If you have updated the repository for KVM hypervisors, restart abiquo-aim

   Code Block
   #> /etc/init.d/abiquo-aim restart

8. For your ESXi hypervisors, we recommend that you go the Storage view and manually delete the old repository

9. On Abiquo Remote Services and Abiquo BPM (V2V), edit /opt/abiquo/config/abiquo.properties

   1. Modify the abiquo.appliancemanager.repositoryLocation property and set the new IP of the NFS.

      Code Block
      abiquo.appliancemanager.repositoryLocation = NEW_IP:/opt/vm_repository

10. Restart the Abiquo Tomcat servers in the following order

    1. Abiquo V2V (BPM)

    2. Abiquo Remote Services

    3. Abiquo Server
