I have a few forums which have accumulated a few years of prefixes to help members ID content and it would be quite a loss.
I faced a similar problem going from VB to IPB a couple of years ago and spent weeks restoring the prefixes manually - can't so that again.
Would it be possible to modify the IPB import script (happy for it to be a paid job) to process thread prefixes by:
1. Recreating the prefix during the import process.
2. Attaching the appropriate prefix to threads.
Would appreciate any ideas on this,
