Miller, the former Scotland internationalist, had two months left on his deal with the MLS side and Rangers are favourites to secure the striker for a third time.
Miller, though, insists he plans to take a holiday before sorting out his future. "There is nothing in place as yet," he said. "What this does is give me six, seven weeks to first of all get a holiday, which I've not had since I've been out in Vancouver.
"So we'll get away and then we can sit down, my agent can earn his money and hopefully find me a new club come July 1. I wouldn't rule anything out, I'll can look at all options to see what it brings.
"It's a case of my agent getting down to work and finding a new home. For me it's a good time to go."
