Aem - best way to install AEM Service Packs to AEM

[robertol6836527]

Good morning,

What is the best way to install AEM Service Packs to AEM Author and Publish Instanced ?
I have more publish instances.
Is there any official documentation ?

Searching on the web there are two different procedures:

--- First procedure ---
- Log in to the Author machine
- Go to http://<host>:<port>/crx/packmgr/index.jsp
- Upload the Service Pack
- Install the Service Pack
- Replicate the Service Pack from Author to Publish

--- Second procedure ---

Procedure to be performed on the Author machine:
- Log in to the Author machine
- Go to http://<host>:<port>/crx/packmgr/index.jsp
- Upload the Service Pack
- Install the Service Pack

Procedure to be performed on each single Publish machine:
- Remove Publish out of load balancer
- Log in to the Publish machine
- Go to http://<host>:<port>/crx/packmgr/index.jsp
- Upload the Service Pack
- Install the Service Pack

Which is the best of the two procedures or is there a better one?

Thanks

SP are heavy bundles, and needs to perform many dependency resolutions, and update and restart many services. I do not recommend installing SPs via the package manager, rather put SP in the install folder of your repository and restart the AEM instance. See the below articles for details.
