I am planning to migrate my Redmine (1.0.5) to a new machine. I would like to upgrade Redmine to latest version and change the database from MySQL to Postgresql with this migration.
My plan A is:
- move Redmine 1.0.5 to new machine with database
- upgrade Redmine 1.0.5 to latest version
- migrate database from MySQL to Postgresql
plan B:
- upgrade Redmine 1.0.5 to latest version
- migrate database from MySQL@MachineOld to Postgresql@MachineOld
- move database to new Machine
- move Redmine to new machine
plan C:
- migrate database from MySQL@old machine to Postgresql@new machine
- install latest Redmine on new machine with migrated db (1.0.5) and do database migration (1.0.5 -> latest)
There are many possible ways to do this job. Which way do you recommend? After step 0: make a good backup.
