Hi,
I am trying to upgrade Microsoft Exchange 2016 CU19 to CU23 in an Hybrid environment with Edge Transport server available in same setup.

Setup:
2 x Exchange 2016 Mailbox Servers on CU 19.
1 x Exchange 2016 Edge Transport sever CU 19.
4 x Domain controllers.

Please advise me.

My question is do I need to perform any additional steps inoreder to upgrade exchange mailbox severs & exchange edge servers to CU23 as we have o365 Hybrid configurations?

is it going to remove all connectors on exchange edge server if I upgrade to CU23? please also share how to change edge certificate as we copied our on-prem mailbox server certificate to exchange edge server and currently edge sync is not working.

Do I need to re-run Hybrid configuration wizard on primary exchange server 2016(mailbox server) after CU upgrade?

Do I need to backup exchangetransport config files before upgrading? Also, our exchange delegation federation certificate is expired please advise how to renew it as it is self-sign certificate.

Please advise.

Thanks
ATFRMZ

    You could update Exchange to the CU 23 directly.

    My question is do I need to perform any additional steps inoreder to upgrade exchange mailbox severs & exchange edge servers to CU23 as we have o365 Hybrid configurations?

    No.

    is it going to remove all connectors on exchange edge server if I upgrade to CU23? please also share how to change edge certificate as we copied our on-prem mailbox server certificate to exchange edge server and currently edge sync is not working.

    You don't need to copy any certificate. Exchange Edge use a self-signed certificate. You could follow this article to remove Edge Subscriptions and create a new one.

    Do I need to re-run Hybrid configuration wizard on primary exchange server 2016(mailbox server) after CU upgrade?

    It is suggested, but not needed.

    Do I need to backup exchangetransport config files before upgrading? Also, our exchange delegation federation certificate is expired please advise how to renew it as it is self-sign certificate.

    You could backup this file. About delegation federation certificate, here is detailed information about it: Renew the federation certificate
