Hello,
I'm in the early planning / testing phase of preparing to migrate our staff from on-prem DC's & Exchange 2013 to MS365 and Exchange Online.
Looking to have a hybrid AD solution in the end so authentication can occur on premise using our DC's, and when off-net they can use AzureAD. I believe the AzureAD Sync Tool will assist with 2-way synchronization so account records are kept up to date.
We have around 100 staff, that will be migrated, and we'll be setting up a domain alias because our on-prem domain was a ".local" domain.
Has anyone gone through this sort of process before, if so what was your experience like?
Were there any gotcha's or major issues that you came across?
After completing your migration, was there something you wish you knew at the beginning that would have saved you time?
Thanks in advance for any feedback.
Password hash sync is definitely worth it. I also agree on the subject of UPN matching email address. I've got some legacy apps that cause all kinds of problems if we change a UPN, and I have a mixture of users where their UPN is definitely not their email address - and that's just something I have to explain over and over again.
