Re: Xsan-Users Digest, Vol 58, Issue 11

I have never had an issue with an upgrade. You need to be patient and  
follow all the steps the biggest issue is that once you have upgraded  
you need to do nothing. In my experience it's about 1 hour per  
1,000,000 files to reprocess the metadata. As indicated you should  
always have a backup with any major upgrade.

Cheers,

Rick
