Nevertheless, the dad-of-one is looking forward to starting his new breakfast show on the Dublin station this Monday.
And he's not nervous, comparing the experience to putting on some old slippers.
"I know all the producers and a lot of the guys working on the show," Ray said.
"It'll feel very familiar, like I'm putting on an old pair of comfy slippers," he laughed.
This week new presenter KC took the helm at Ray's afternoon show on Today FM.
Ray says they share a lot of traits: "He's tall and from Mayo and overweight like me. He's much nicer, though."
Ray and sidekick JP have been doing a few test runs for the new show.
"I dropped my cardboard box of belongings into the studio a few weeks ago and we've done a couple of dry runs with the producers. They've gone well."
But he said that he's missing the crew at Today FM.
"Eight years is a long time; it's emotional making any sort of career change after that length of time.
"Six of those years were spent on lunchtime shows. I bought my first house, adopted a dog, got married, had a kid, got drunk a lot and won a few awards in those six years and it all happened on the air on the show," he said.
Ray took to his blog to say goodbye to his listeners.
"I just wanted to drop a note to those of you who've been listening to us for the last several years," he wrote.
"We would hate for you to think we're just pissing off without a thought or a mention of you."
The Mayo native said he was looking forward to the early mornings and spending more time with his son, Matthew.
"Matthew is seven months old and I want to spend as much time with him as he grows up," Ray said. "That was a major draw for me."
