As part of this setup we have 5 ZooKeeper servers running on machines pre-1 thru pre-5. They have been running for several days. (2) At some point, we want to switch the preproduction instance to be the production instance. For the ZooKeeper servers, we will copy the data + logs directories from the pre machines currently running ZooKeeper to the prod machines that will be running ZooKeeper, and start up ZooKeeper on those machines. Is this all that is necessary so that the new ZooKeeper cluster effectively continues from where the pre cluster left off? Am I missing something? Thanks, Satish --000e0cd150b6164fa4046919953c--
