We have been RT testing and Travis testing Parsoid code on 4.x for a while and everything seems good. It is time to start taking steps to move Parsoid to Jessie / node 4.x.
Given change in GC behavior in node v4, the last blocker is doing some memory usage evaluation under similar concurrent loads as production. Given that the migration will have to happen one node at a time anyway, one simple / lazy way of doing this would be to migrate a single node over and monitor it over a 24 hour period. Is this recommended or should I do load tests separately?
Separately, what is involved in getting this process going?
