Hi. Thanks for replying back. Just a quick cross-confirmation, if you don't mind:
So, I can do the following without fearing any loss of data, etc? * "nodetool drain" and bring down the 0.7.0 node (it's a one node setup that I am upgrading) * remove all files from saved_caches directory (both system*-KeyCache as well as application-specific*-KeyCache files) * bring up the new 0.8.5 node (pointing to same "data" and "commitlog" directories) The *KeyCache files can be removed safely in between, right? Cheers.
