Now that you mention they have replication, it definitely is worth re-looking at it. I inheritted courier and at the time we were not growing as fast as we are now.. We used to get smaller accounts so the increase in load was always fairly small and we could extremely easily plan adding more capacity. Now that we have larger orders coming in it's a whole different game.. Eliminating NFS will be one great added bonus.. Will read up on Cyrus.. This replication feature, is it brand new or has it been been tested well by now?
