If you have a large db in 7.4.6, you should do two things.

Sounds like good advice from a strictly technical viewpoint.  

Unfortunately, in our particular real world, there are also 

political, financial, and resource constraints and impacts from 

downtime that at times outweigh the technical merits of 

upgrading 'right now'.

Since you're setting up replication to another database, you might as

well try replicating to a newer release and swap them around once it's

done. I've seen that method of upgrading mentioned on this list a few times.
