Changing the master site

These steps assume the following:

Multiple existing sites all on one intranet, where Site A is the current master site and Site B is another existing site in a different database on the same intranet.
You want to switch the master site to Site B.

Follow these steps:

Ensure that all users are logged out.
At Site A, unshare any _all or user tables that are shared. Keep a record of the tables that you are unsharing. See the help topic "Unsharing Multi-Site Shared Tables."

This could take a long time.

Note: If all sites are in one database, you can skip this step.
In the Intranets form at Site A, set the Master Site to blank.
In the Intranets form at Site B, set the Master Site to Site B.
At Site B, share any _all or user tables that were previously shared with Site A.

This could take a long time.
On the Trigger Management form at both sites, regenerate triggers.
On the Replication Management form at both sites, regenerate replication triggers.
Use the Unload Farm IDO Metadata form to clear the cache for the current configuration, across all servers in a farm.
To clear the cache for all configurations for all sites in the farm, you must log into each configuration individually and unload the metadata.

Verification: If sites are not in the same database, and sharing of _all tables or user tables is in place, verify that the data in user tables at the master site is updated when data is updated in the subordinate sites. Also ensure that views are set up appropriately within the databases.

Note: Never select the Intranet Licensing option in a cloud environment.
