Earlier quoted context omitted.
the FreeBSD migration didn’t take that long - iirc this was the frontend migration to an IIS ISAPI. the Solaris bits (storage and routing tables) took far longer - and again iirc the frontend had been rewritten in C# before all the Sun hardware had been decommissioned.
Ah sounds like you actually might have been there. I'm sure you must have some interesting stories from that time
fun times for sure.
