Yeah - I would bootstrap at initial_token of -1 the current one. Then once that has bootstrapped, then decommission the old one. Avoid trying to use removetoken on anything before 0.8.3. Use decommission if you can if you're dealing with a live node. On Sep 12, 2011, at 10:42 AM, Kyle

The ring wraps around, so the value before 0 is the max possible token. I believe that it is 2**127 -1 . - Original Message - From: Kyle Gibson kyle.gib...@frozenonline.com To: user@cassandra.apache.org Sent: Monday, September 12, 2011 3:30:20 PM Subject: Re: Replace Live Node What
