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.
