Generally, I've done this type of thing by doing something like 4.9->5.0->5.x->6.0->6.x->7.0->7.x Why? Generally updating from Y.X to Y+1.0 is something that has been done many times. Then Y.0 -> Y.X is also straightforward. The fact that I don't go from Y.0 to Y+1.0 is just superstition. The Y.0 rev is very often out of maintenance before y+1.0 is released. Of course, if the hardware hasn't been updated since 4.9, then you're probably going to have buildworld times in the 6 to 8 hours. Oi. If you get to the minimum support level of freebsd-update, the remaining upgrades might be faster through freebsd-update. ... although I've found version upgrades tedious through freebsd-update. It seems to want to manually merge every text file that has a CVS string change. ... it might be good logic to not require a manual merge if the lines that change begin with '#'
