Planning SME to NethServer migration

NethServer Version: NethServer release 7.6.1810
Module: Migration from NethService/SME Server

I am currently running SME Server 8.2 and plan to migrate to NethServer release 7.6.1810. I have configured NethServer on the new hardware with the services that are required.

For the migration I am following the documentation at http://docs.nethserver.org/en/v7/migration.html and plan to use the “Sync and migrate” procedure. I have successfully run the following command on the new server:
screen rsync-migrate 10.0.0.5 22
where 10.0.0.5 is the old server
I now wish to run the final command:
screen rsync-migrate -m 10.0.0.5 22

My question is: If there is a problem on the new server, how do I get the old server back on line again? Will it have been modified in any way, or can I simply disconnect the new server and reboot the old one?

On the new server, what happens to the data if the migration fails? Will the transferred data remain in /var/lib/migration, which means that it makes it easy to rerun the rsync-migrate -m command after fixing any problems? Or will all data have to be transferred a second time from the old server?

Turn off the new one and power up the old :slight_smile:
The configuration will not be changed on the old server.

Yes but only for the failed actions. Successful actions will move data to the right place.
