This is what most people do I believe - if you have an Advanced Services
contract with Cisco you can get them to prepare a report recommending a
code release but they just look at the latest version and most suited code
train for your requested feature set and compile a list of known bugs
affecting features you request. It's a useful report to have for a large
scale deployment however, if there are minor bugs that you're not too
bothered about at least you know the workarounds in advance.
If you don't hit a serious bug, it's best not to upgrade - we've had one
potential customer request that we always run the latest or latest-but-one
release of software on our network gear - we told them no way. It takes too
much time and you can cause a lot of downtime introducing new bugs into the
network this way.
There's a minor routing table bug in the version of IOS I use on our Leased
Line routers, but we've not upgraded even he routers it affects - we know
a workaround, we'd rather not have different IOSes on different routers
performing the same function and I'd rather not risk introducing some new
bug that we don't have a workaround for into the network!
