MACRS Convention Switch - how long can it take?

SUGGESTED

We have an almost-last-minute switch to midquarter for MACRS. There are about 8,000 asset additions and I have completed about 250 transfers and 800 disposals (with more to go). I started the switch to midquarter yesterday, so it has been running for 24 hours now. I am on a VPN and do not have the ability to be directly on the network. It was slow going yesterday but the bar was moving (turning green). After 6 hours it was at about 90% and has been that way ever since. Is it stuck? Or is this normal with the amount of assets and I just need to keep waiting?
