Sharepoint 2007 (MOSS) Upgrade - TempDb issues

In the middle of a Sharepoint 2007 (MOSS) upgrade....

One key piece of advice I can give - allow TempDb to have PLENTY of space when doing your initial full crawl.... in fact you may find that the % increase approach may not work during this process because it can't get enough space to fulfil it's very hungry needs! A Mb increase approach should work fine.

You may see errors such as "The transaction log for database 'tempdb' is full."

During later incremental crawls it shouldn't need any special handling, this just seems to apply to the intial full crawl.
