Hello, have you tried tailor (http://progetti.arstecnica.it/tailor) I've had good experience with it converting perforce to svn, a branch with about 220 K changesets on mid-end workstation HW (4 GB Ram / Dual-proc dual core Xeon 1.8 GHz) I can't remeber the total time it took, but it was in the 2-4 days range. tailor keeps state of where it is in the process of migration, so it can restart at the same place in case a problem needs to be manually solved. The process was more IO bound than CPU bound, I don't know how well it handles cvs though. -- Vincent Legoll
