YAM and message archives

[Matt_H]

Due to a shortage of hard drive space, I used to back up my YAM mailboxes to CD, delete them from the hard drive, and basically "start anew" every time I did a backup.

Now that I have essentially unlimited disk space, I want to bring my archives back into YAM for easier searching. I'm concerned because:
1. Some of the backups are in the old YAM 2.4 format. If I dump these files into my inbox directory, will YAM correctly identify and convert them if there are already a bunch of newer 2.5-format mails in there?
2. How does YAM set filenames for messages? Worried that, for example, message 45 of backup 1 might have the same filename as message 45 of backup 3, even though they are different messages.

Thanks for any insight!

I think you could run this test yourself.
Just add one old format message to a YAM folder of your choice in the new format and select "update index" for that one folder only. In that way, you won't affect any other folders.
After the update you can compare your message pre and post conversion.
Beyond that, I can only advise backup prior to any major changes, which is obvious advice I know...

A single message test? Why didn't I think of that?

I'm pleased to report that YAM correctly converted the old messages and I now have my gigantic archive. Thanks!

New question (though related): Using the Import... menu option, is YAM smart enough to avoid/skip duplicate messages? Anyone know?

Thanks.
