I am upgrading my servers and instead of migrating which is a lot of downtime, I opted for HDD swap. The web host as suggested that there may be data loss if swapping takes place.
I am running RHEL 5, RAID
Will there be data loss?

Any time you move disks around, there's a chance for data loss, stemming from many possible causes including but not limited to:
All this to say that if you have backups, don't worry about it. If you do not have backups, do not migrate nor doing anything else on your server until you're sure you have watertight backup and restore procedures down pat.
The chances are fairly slim of any of the above things happening, but the chances are non-zero, so you need to do your due diligence in preparing for the migration by double and triple-checking your backup situation.
