My team is looking to reconfigure the topology of two search service applications on an SP2013 farm.
We need to make this change because there are multiple components from different SSAs on the same server (which is not supported by Microsoft) - so we plan to move the components that are the same across SSAs (e.g. Admin from SSA1 is on Server01, though Admin from SSA2 is also on Server01 - so we need to move this to Server02).
The two SSAs are used because one must be isolated from our main SSA - as it is a dependency of a third party application (which must use its own search schema etc.).
We would like to perform the reconfiguration with minimal downtime and therefore perform the search component adds / removes in bulk.
We're comfortable with moving a single component (e.g. as per here: SharePoint 2013 Search Moving Query) though have concerns about moving multiple components in the one go (e.g. adding multiple components in at step 2 of Steve Mann's post above, and removing multiple components at step 7 of the post).
Is anyone aware of any issues / gotchas with moving multiple search components in one go?
Naturally we would change the topology for one SSA at a time.
Thank you!
