Yes this is possible. You have to install 3.x on another server than 2.x and use the same DB. Beware: The database location is stored in the DB itself. Therefore if you used "localhost", this will not work from the second machine. If you used an DNS Alias (e.g. defined in /etc/hosts) > I would imagine I need to run the database schema update to 3.0.0 (via > sql-update-3.0.0-to-combined-mysql.sh), No, not at all. That script is only needed, if you want to change to the new db schema with only a few tables for all users, instead of 6 tables per user. Then you have to change the SOGo configuration too. > but will this make any changes to the database that would be incompatible > with 2.3? Yes, 2.3 is not capable of using the new schema (yet?). > And also, does 3.1 store data any differently in any existing tables that > would cause a problem? > If you keep the existing db schema, it will work without problems.
