Migrating instances to a new machine

Questions
1

I’ve moved to using AMP in a VM over its original home on a standalone server, and now I’d like to move my instances over from the old HD and I’m not seeing how I can do that. Is this even possible?

2

once you’ve installed amp on the new ‘system’ go to your old datastore location and copy the whole “Instances” folder over to the new datastore. restart amp and should work no problem

3

You can do that or you can create a backup of the instance and copy it over and restore it.

4

My problem is, it doesn’t give you the option to restore, even after the backup is transferred over to the new “back up” directory.

5

You treat it just as a normal zip file and extract it.

Hello,

I have spent hours trying to migrate from one linux server to another. I am not a linux admin guru, but I am an IT professional and have plenty of experience. I have 2 linux servers with SSH/SFTP access between them. I could not find any good articles here or on YouTube to do this, so I pieced together the steps below from what I could learn. However, it isn’t working. The Amp console reports no instances, but I can see the folders in the console when I go to File Manager and click into the “”__VDS__Datastore-DefaultDatastore" folder.

  1. SSH into old server and go to .ampdata folder in /home/amp
  2. tar instances folder
  3. Use SCP to get tar file from old server (file copy via SSH). Exit old server.
  4. SSH into new server. Confirm file copied.
  5. Use sudo tar to extract instances archive back to original location (run from root /)
  6. Use ls to confirm files
  7. Run ampinstmgr fixperms
  8. Reboot server
  9. Login to Amp console (note: password changed to password used on old server)
  10. From Main Menu > Datastores, run “Repair”

Consoles shows no instances. :frowning:

Any guidance here? Thanks.

Guide to migrate individual instances by hand:
https://discourse.cubecoders.com/t/moving-instances-from-one-amp-server-to-another-with-existing-instances/18341

The following are a general list of steps that would be a tad safer migrating all your instances across systems, and doesn’t require the repair step.

Note, to log into the amp user you can run (su -l amp or sudo su -l amp [lowercase L, not a 1])

On the old system:

On the new system do the following:

  • install AMP
  • as amp, run ampinstmgr stopall
  • stop the ampinstmgr service (service ampinstmgr stop on debian)
  • nuke/remove .ampdata (or just rename it to be safe, you never know)
  • restore your own .ampdata folder on the new machine
  • as root, run ampinstmgr fixperms
  • start the ampinstmgr service (service ampinstmgr start on debian)
  • as amp, run ampinstmgr reactivateall
  • reboot if things look funny

TPK,

Thanks for posting this! I learned a lot going through the process with my method. I feel better knowing if I have to do it again, there is an “official” guide!
