[MM3-users] import21 detailed usage instructions in 2024

 1 Soon, I will be executing the first test imports from

Mailman2.1 to Mailman3.9.

 2 Planning to copy over the entire production Mailman2.1 to a new

directory structure on the Mailman 3.9 machine.

 3 Expecting that all .mbox and .pkl files will be present and no

special work has to be done to bring them over will a "full" mailman2.1 copy.

 4 Can the import21 program find the mailman2.1 .mbox and .pkl

files on its own and process them?

 5 Other than the mailman2.1 instance being shut down, any other

prep that needs to be done?

 6 Any special command line parameters to be aware of for import21?

 7 Is there a list of troubleshooting steps for commonly

encountered migration issues?

Thanks.
