-->Can I do it from CU 6 to 21/22 directly?
Yes you can upgrade directly to 21/22

First upgrade to latest CU and then re-run the hybrid setup.

Resolution
To resolve this problem, follow these steps:

Install the latest cumulative update for Exchange Server 2013. To download this update, go to Updates for Exchange 2013.
Run the latest version of the Hybrid Configuration wizard. To download this, go to http://aka.ms/HybridWizard.

Hi,

I´ve CAS certification problems. Certificate is old and I need to renew but no ECP/OWA up

How to do this?

Using IIS or powershell?

You mean CAS server upgraded but not able to access ECP or OWA?

What is the error message?

Or you are looking for an option to update the certificate?

CAS Update

Error at MBX

CAS rollback and now, self signed cert error.

-->I´ve CAS certification problems. Certificate is old and I need to renew but no ECP/OWA up
u dont need certificate for ECP/EAC

please share the error message or the screen capture - hiding your server names, IP etc..

Hi,

resolved playing with certs and CAS Server.


One question... could be upgrade 1st CAS to CU22 and, several day after, MBX to CU22?

Several Days cannot keep on old version.

Better do upgrade for both on the same time 1 first then after completion start the upgrade of 2nd mailbox server.

Hi Heze54,

Upgrade order that I shared like CAS first and Mailbox later is the one which we follow in Our Environment.. we don't see any issues so far in that approach.. still we are using Exchange 2013.. we follow the CAS first order.. but we upgrade both server roles on same change window.

But few recommendation on Internet says.. Mailbox First and CAS Next.. No need to get confused on that.. that is what recommended in internet.. but CAS first and Mailbox next will also work.. No need to get confused..

CU 6  and CU 22 is completely different so.. better upgrade the mailbox server also.. now itself.

This was the error at MBX CU22 install time

I think, http://www.microsoft.com/downloads/details.aspx?FamilyID=8c8c793a-e7a1-4cfa-a3b2-98eca274a0c0 must be installed.. before CU22, correct?

Agree with Rajkumar install CAS then MBX.
And upgrade the mailbox server as well do not run exchange servers with different CUs.
