Actually, any time you change tuner hardware /or/ tuner drivers (and a 
system upgrade to a new distro version will almost definitely change 
tuner drivers), I /highly/ recommend you "Delete all capture cards" (and 
not "Delete all capture cards on <host>".  So, even if the tuner 
hardware is the same (or a like-for-like replacement), you should 
probably "Delete all capture cards."

If the tuners are like-for-like replacements, then the Video Sources 
should be the same as they were before.  If that's the case, there's no 
need to "Delete all Video Sources", and that means there's no need to 
re-scan channels or anything.  However, if there's anything different 
about the tuners ability to receive certain channels or how they go 
about tuning the channel (i.e. going from a PVR-150 using internal tuner 
to using a PVR-150 using S-Video output with a channel change script 
that changes channel on an STB), you will want to "Delete all Video 
Sources" and re-create the source and re-scan for channels.
