[MM3-users] Issues with importing archives from a particular list

Hello,

We are trying to import archives from Mailman2 to Mailman3. For a particular list, it is not importing all of the messages. We can see that Mailman2 has archives from 2015 to 2022. But, it only imports messages from 2018 to 2022 to the Mailman3 server. It was not giving any errors while importing.

All other lists are imported successfully.

Any idea what was causing the problem?

Kind regards, Prasanth
