Technical How long does the character merge takes?

[ub4o13]

I started the manual merge to Icecrown yesterday and today they are not trasferred yet.
When I go to "My Account" page it says " transfer from Ragnaros to Icecrown is starting." for all my characters and when i to to "Merge" page, it says "Merges have concluded."
There is no estimated time, and I could not find a topic in the forums saying how long it should take.

I've got the same issue here, i started the merge 21 hours ago and i've checked the "My Account" page 20 times but no change.
Does somebody know how long it may take?

My chars have just been migrated, it took for me 20-30 hours.
