Run

The following command runs a simulation, logging into both servers, checking the number of emails and total data volume to be migrated. Highly recommended to run the script first in simulation mode.

python migrate.py --simulate

If everything looks fine, run: python migrate.py

Be aware: for larger mailboxes this might run hours.
