I started the exercise with a view to use migrate export/import.
./migrate export /tmp/gaia-r80-mgmt-2019-12-09.tgz
However the export fails each time with the following message:
Copying required files...
Execution finished with errors. See log file '/opt/CPshrd-R80/log/migrate-2019.12.09_12.32.06.log' for further details
Reading the log file doesn't particularly make any issues obvious, but I see the following lines (which still doesn't add up):
