From Rothgar on the EQ2 Forums:
Things are going very well and considering the extra time we expected from moving the data a long distance, we’re actually running ahead of schedule. Our QA department is checking things out now and if we don’t find any issues we hope to have the server up early.
Thanks for your patience during this downtime!
and later:
Update:
We are still having some issues with the chat portion of the merge, its just taking a little longer than expected to move friends lists, mail, etc.
Everything else looks good so as soon as I have more info, we will let you know.
