[ic] upgrade FAQ for IC 4.8?

[Dave Stevens]

I've looked on the site and list archives, but I can't find any upgrade
info yet.  I ordered the books last Friday.  Specifically, we have an IC
implementation that was modified by Akopia late last year that we would
like to upgrade.

Is there anything to look for specifically for compatability with IC4.8
being upgraded from 4.6.1?  What exactly gets upgraded, and is there a way
someone has found to migrate custom 4.6 apps to 4.8?  We've got a few
custom features built in that aren't included in the standard dist, but
would like the performance and security enhancements of the latest version.
I suppose I could try to merge the 4.8 dist into our current tree to see
what the diffs were, but thought I'd check to see if anyone else had a
better way.

Any pointers or suggestions would be greatly appreciated.
