2010 SP 3 Migration to Hosted Exchange (O365)
Hi drawson
I'm about to do the same for one of our clients. Most of the documentation I've read just mentions needing SP3 but having it on the latest release to maximize chances of successful migration. My client is currently on 14.3.361.1 RU 18 which isn't too far behind, but I'm going to be updating the latest RU for avoidance of doubt.
https://docs.microsoft.com/en-us/Exchange/hybrid-deployment-prerequisites mentioned that it needs to be update to date to be supported if you are looking to do a express hybrid migration. Might be worth updating anyway just in case things do go down south and you need to call in Support

Hi HidMov
Thanks for the reply. Very helpful. What is your standard practice for installing the Exchange 2010 patches? Do you favor installing the latest patch no matter the beginning version? Or do you prefer to install each individual patch building up to the latest? One mention in reading noted it was safe to install the latest update straight away.
We are performing the hybrid migration as we will make the local mailboxes available until they have completely replicated to hosted exchange. Not sure if that is considered express hybrid migration or not.
Thanks.
Hey drawson
I've never had a problem jumping from, say, rollup 10 to rollup 25 though it's been a while since I've had a server too far behind. Double check the pre-req's on the latest rollup just to make sure there are no gotcha's, but generally should be ok to go to the latest.
