i have move the site from a server to a other server, and i have change the dns with the ip of the new server, but a lot of customers not have closed the forum ask i asked so a lot of peoples have post on the old server and other on the new server cause dns propagation, how can i solve this problem? can i merge the 2 dbs?
Usually when I assist customers with moves, I will do the following:
1. Shutdown forum on original server.
2. Copy files and database to new server.
3. Install database and forums on new server.
4. Edit the old location/server to point to the database on the new server.
This allows the forums to be viewed from either location but only updates the database on the new server.
To answer your question directly, I don't know if they can be merged or not.
