I just finished doing the same thing - I moved the contents of my 55 to my new 125 without incident around 2 months ago. I just added the make-up volume in new (aged) salt water and everything was fine. No ammonia spike, not a single loss, etc... Not sure how this has worked out for other ppl but for me it was totally painless.
