NS7 -> NS8 Mail migration stalled

After selecting the “Finish migration” button, I’m now at this:

What can I check to see where in the process this is.

  • Has is actually started
  • Is it stuck somewhere in the middle
  • Has it finished

Cheers.

Try following the logs:

  • The migration tool UI has a Logs page for reading /var/log/ns8-migration.log contents. The migration procedure of each application sends a trace of its activity to that file.
  • Furthermore, when joining/leaving the NS8 cluster and when NS7 services are modified, some information can be recorded by /var/log/messages as usual.
  • On the NS8 side, the application log contains the trace of the import-module activity.

There is a bug with roundcubemail-next (don’t know it that concerns you …maybe is unrelated to the current migration stage), and a bug with remote ldap account provider.

Can you ssh in and check with top what processes are running and the load. Maybe this tells you something about activities.

Nothing out of ordinary running and very low load on both servers, so nothing soaking cpu on either side.

Nothing other than the creation of files/directories and the initial sync. Nothing logged about the Finish process.

Not using roundcubemail and my NS7 provider is the Samba based AD.

At the end of the application migration, the system will:

  • start the module inside NethServer 8
  • disable the application inside NethServer 7

Definitely not got that far. All the ports are still open on NS7, none on NS8.

Not sure what was wrong, but fixed it by following the following sequence:

  • Disconnected NS7 from NS8
  • Un-installed the migration package from NS7
  • Re-booted NS7
  • Re-installed migration package
  • Re-built NS8 from the Rocky image
  • Re-created the primary cluster
  • Re-connected NS7 → NS8
  • Performed the mail migration

Cheers.
