Maintenance Releases Deployment Best Practices in AEM

Adobe releases maintenance fixes in duration of some months based on the issues raised by licensed vendors or internal clients etc. Previously it was known as hot fixes, but now it has changed to 'Cumulative Fix pack' & related 'Service Packs'.

Precautions & Best practices: Ensure you always follow below step;

  1. Test in Lower environments first and then move to prod for any maintenance pack deployments.
  2. Ensure you have done a proper back-up of content, DAM and code.
  3. Validate the new package before install

Curl Commands Vs Package Manager?
CURL is a command line version of package manager. Package manager provides the UI to deploy packages.

We recommend using CURL commands if the package size is big(They execute faster through CURL)

Analyzing the Activity Log on package installation:

We can see a BOLD highlighted letters while installing a package through package manager. Below are the notations.

A : Added new content/code to specified path.
D : Deleted content/code.
U : Updated
- : No action taken (remains as it is )
E : Error on path.

Sometimes admin face issues with new packages like unsatisfied package imports or Overlay issues.

How to validate a new package for issues before install?

On package right side, click on More> Validate and select the check boxes and click on 'validate'. The validation and and any issues which exits can be verified through 'Activity Log'. Contact Adobe if any issues are observed.

Once above precautions are followed(Including a lower environment successful deployment), deploy the maintenance pack in prod, then restart  AEM. Clear any cache, test and validate the package version then verify the project related checkpoints at PROD. This steps helps an admin to install a cumulative pack smoothly.
