I am able to install v7.2 with the statefulset config that is listed below, but for a service I'm running, it hasn't been updated to support v7 yet. Currently, the service only supports v6.3. The following is the error I get when trying to boot up the statefulset.

Error log. Too long to include it in OP.

You are attempting to downgrade a node in place. The data on disk was written by a 7.2.0 node so cannot be read by a node of an earlier version.
If this is a new installation then your best bet is to wipe the data path and start again. If you need to preserve the data then you will need to do a reindex-from-remote to get the data back into the old cluster.

Ah of course; I don't know why I didn't think of that. When upgrading from 6.3 to 7.2+, will the new installation be able to utilize the database, or will I need to re-index? It's not mentioned in the upgrade docs.

**Upgrading** in place is fine, indeed it's normally the best thing to do. It's just **downgrading** that isn't supported.
