Again, it is strongly recommended you test this first. However it is not recommended that you run a cluster with a mix of 7.x and 8.0 code for any significant length of time, just the time required for a rolling upgrade. Important things to note if you decide to upgrade an existing 7.x system: -- 8.0 always runs with an on-disk database, in-memory databases are no longer supported. Improvements made late in the 7.0 series means there is little difference in write performance between in-memory and on-disk modes, but supporting both modes just meant confusion and higher development costs. If you were previously running in in-memory mode (the previous default), you don't need to do anything. But if you were previously passing `-on-disk` to `rqlited` so that rqlite ran in on-disk mode, you must now remove that flag. +- 8.0 always runs with an on-disk database, in-memory databases are no longer supported.

If your cluster is already formed, upgrades will work without changing anything (`-join` options are ignored if nodes are already members of a cluster). You may need to change any scripting or automatic-configuration generation however. - A few rarely, if ever, used `rqlited` command-line flags have been removed. These flags just added operational overhead, while adding little value.
