Hey,

I'm just standing before update of our stand alone Exchange 2013 CU1 server to CU7. Is it OK to do this update this way or should I start with patching lower CU's like SP1 and then CU7. Are there going to be serious problems or no at all? I have to do this update on production system - unfortunately no test environment is possible in my case.

Do you recommend any advanced process during installation of this CU that differs from manual on TechNet? Are there any critical post-update todo's? We are using OWA (with IIS modified to support only SSL access, ActiveSync). 

Thanks, best regards

Matt

Hi Matt,

this Upgrade is supported so shouldnt be an issue.

this is simple guide i follow during CU update:

1. Run latest windows update

2. Server Switchover (skip since you have only 1 server)

3. Uninstall UM Language Packs (if you have any installed):

setup.exe /RemoveUMLanguagePack:de-DE setup.exe /RemoveUMLanguagePack:da-DK setup.exe /RemoveUMLanguagePack:fi-FI setup.exe /RemoveUMLanguagePack:fr-FR setup.exe /RemoveUMLanguagePack:nb-NO setup.exe /RemoveUMLanguagePack:en-US

(where setup.exe is run from install dir of CU you extracted)

4. Setup.exe /PrepareAD /IAcceptExchangeServerLicenseTerms

5. setup.exe /mode:upgrade /IAcceptExchangeServerLicenseTerms

6. Run Latest windows update

7. Install Language packs

There are some issue With Latest .net so i recomend you avoid it before installing this With CU7.
