Remove orphen SQL witness store from Skype for business topology

Note: Editing the topology manually is not recommended. Be extremely careful when removing the items.

Please take a backup of the CMS and user data before making any change to topology.

Download the latest topology and open the document using xml editor or wordpad. Search the orphen witness store name and find the Unique ID highlighted below.

Search again with unique key id and find the associated witness store name.

Remove the service entry from the topology , starting from </service>line , remove for lines highlighted below. There are two places you could see the services entry for the SQL witness store , you should remove both. Make sure that there is no space between previous like and alignment is correct.

Remove dependency for the witness store. You should remove two lines highlighted below , changes are needed in multiple places where witness store is associated. Also change the next line in each places according to below step.

Once above two lines are removed , next ‘DependsOn’ entry should change from <DependsOn> to <DependsOn />. (Changes needed in all the places )

Save the topology file in TBXML format. Open the saved file using topology builder and validate the information. Now you should be able to remove the SQL witness store and publish the information.

If you get any error while opening the topology , you didn’t remove all entries from topology or there may be space or additional characters near the change.
