The south of Scotland facility shut last year despite a local campaign for its retention.
A report to Dumfries and Galloway Council said the new service was proving of a "high standard".
However, it said changes to IT systems meant "direct performance comparisons" were not possible.
The Dumfries site was the first of a number of control centres across Scotland to be shut as part of plans to modernise the service.
The union Unison described it as a "sad day" for the town and more than 30 staff involved.
A review of its impact has claimed that many figures could not be directly compared between the old service and the new one.
It did find satisfaction levels were "consistently above 90%".
The report also revealed that just nine out of the 34 staff affected now remained with Police Scotland.
It concluded that the public and police officers in Dumfries and Galloway had benefited from the larger operating model and more modern IT systems.
Although it had been a "significant change", the report's verdict was that it had performed "to the satisfaction of the public".

Guitarist and co-songwriter Johnny Marr has released an extract  from his upcoming memoir Set The Boy Free in the Guardian and said he met with former band mate Morrissey in 2008.
The pair discussed the possibility, which Marr said would "make a hell of a lot of people very happy".
But "the distrust remained" between the two and the idea never came to pass.
Marr was back in touch with Morrissey in a "rare period of communication" when he was remastering The Smiths' back catalogue and they arranged to meet in a pub in south Manchester.
"I was happy to see him," he wrote. "It was 10 years or more since we'd last met. We caught up with personal news and family and reminisced a bit."
But then the conversation turned to "deeper things" and, eventually, what Marr called "that subject".
He wrote: "There had been rumours for years that the Smiths were about to re-form, and they were always untrue. I had never pursued any offer.
"Suddenly we were talking about the possibility of the band re-forming, and in that moment it seemed that with the right intention it could actually be done and might even be great."
After parting company with a hug, Marr returned to his band at the time, The Cribs, and talked to them about him possibly playing some shows with The Smiths, which he hoped "might even be better than before".
But by the time he returned from Mexico with the Cribs, Marr said, the communication had ended.
"Things went back to how they were and how I expect they always will be," he said. "An air of disaffection and distrust remained between us. It was a shame."
A report has found the police control room service has "performed well" after closing its Dumfries site and moving provision to Glasgow and Motherwell.

A founding member of The Smiths has revealed that re-forming "was a very real prospect" - if only for four days.
