Thread:Project:Support desk/Migrating from 1.6.7 to 1.16.4

We have 2 servers. One old and 1 new. We have an old install 1.6.7 on the old server with a full wiki and a new empty installation v1.16.4 on a new server. We need to migrate all the data from the old server to the new. How do we go about doing this?
