Hi Team,

 

I have exchange 2010 and plan to migrate to Office 365. I have +- 50 mailbox.

My requirement is, I need to demote all Exchange in On Premise and use Azure AD Connect to run PHS.

 

what method is best suited to meet these requirement ?

 

Thanks

Regards

Ichwan

Hi
According to Microsoft this is not a supported scenario. When using ADconnect there should be an instance of Exchange running On-Premises. There are a free Hybrid license for Exchange 2016 also, if no mailboxes live onpremises.

To read more about this and different scenarios, please read here:

https://techcommunity.microsoft.com/t5/exchange-team-blog/best-practices-when-decommissioning-exchan...

https://docs.microsoft.com/sv-se/exchange/decommission-on-premises-exchange?redirectedfrom=MSDN

Although, many DO remove all servers even in this scenario. It’s up to your org to decide here. To remove exchange totally there’s plenty of guides step by step online

Hi@adam deltinger ,

 

how about cutover migration, demote exchange, last running azure ad connect and perform hardmatch,

is it possible ?

 

or how about staged migration, is it possible?

 

Thanks
