We are IFS hosted.

In IFS Apps 9 UPD 1, on the Solution Manager -> Security -> Users -> Active Directory User Integration screen, there is a Primary LDAP Server listed.
We need to change this server. 

I know when we updated the password for the service account listed on this screen, we lost IFS access and IFS (who hosts our system) had to stop/restart some services for IFS to work again.

Do we need to coordinate with IFS to change the LDAP server name? Or are we able to do that with no other impacts?
