Let me qualify this by saying this question relates to future planning purposes only. We recently upgraded our DEV and DEV DR clusters from 7.0.14 to 7.1.4. I noticed in there are now two versions listed in our software directory:
15:57:09 [memsql-admin@CH-D-MEM-AGGR1 ~/scripts][Dev]$ cd /opt 15:57:14 [memsql-admin@CH-D-MEM-AGGR1 /opt][Dev]$ ls -l total 8 drwxr-xr-x. 5 root root 121 Jul 17 2019 chef drwxr-xr-x 15 root root 4096 Mar 28 16:41 memsql-server-7.0.14-e9a36d3e69 drwxr-xr-x 16 root root 4096 Jul 14 19:02 memsql-server-7.1.4-516dfe4088
My question is, in the event that we would need to rollback to the previous version, what would the path be given that we do currently take nightly incremental backups of all our databases in the cluster and a full prior to the upgrade?
