SQL Server Merge Replication Change Partition Definition
I found a solution!


Go to the merge agent that handles the subscriber that you would like to change.
Right click -> Properties
Go to the Steps page and edit the Run agent step
Add or Alter the HostName parameter like so:  -HostName [&lt;Your Value Here&gt;]
Stop &amp; Start the agent job
Reinitialize the subscription.


That should do it!
