I have to say that shifting servers has gotten much easier over the years with the way in which WHM has evolved to really get inter-server transfers spot-on. Bar one minor issue forgetting to have memcached installed on the new server, each account transferred beautifully and just works. Always a little bit of a headache though I feel... especially those sites on dedicated ip's that then do take the full 24 - 48hrs to propagate vs. a couple of hours for those who share usually the main ip. Having to fully shutdown a site for that period tends to upset a few people... especially forums. Doh! ServInt is an excellent host, but they simply become too expensive at the upper range when one begins needing cores and cpu's allocated vs. other competitors who then come in around 40 - 50% cheaper for the same grade equipment / near identical specs. It was the only reason I moved... I ran out of CPU, needed more, but their upper-end pricing is just too expensive compared to the competition. Been a damn good host for 5 years now and hate to move from them, but so far it seems promising.
