[Mailman-Users] Importing archives

[Rakshika Bhana]

Hi

We have recently migrated some of our lists from Lyris to Mailman 
but are experiencing problems with importing archives.

We have managed to export the archives but when the archives are 
imported they appear without any visible thread. The archives of new 
lists that have been created on Mailman appear fine. 

Is there something that we're overlooking?

Thanks
Rakshika
