Having done a lot of M&A focusing on operations I would say if they have the space at either location you merge the operations.
Getting rid of 1 site with the fixed costs and looking for synergies in the customer service teams and back office to pay off the cost of acquisition.
I can think of several sites where multiple companies are hosted by one CS team. The CS folk see on their screens which firm the customer is calling.
The trick of course is to establish who are the must keep staff & move the operations in a low sales period rapidly after any announcement. ERP systems will also need merging.
My guess depending upon the challenges is 6 - 12 months tops if that is their business plan.
