Patch Installation steps in SharePoint 2010

Hi,

1.What are the steps involved in Security update installation?

Below are the steps for installing any Cumulative Update/Service pack/Hot Fix/patch on SharePoint Farm (with multiple server scenario).
  • To be on safer side take copy of Inetpub and 14Hive (15Hive, 12Hive) folders.
  • Make note of Previous Upgrades from Central Admin(CA). Also review "Health Analyzer" reported issues on CA.
  • Make note of the BUILD number (farm version).
  • Install the patch on all servers in the Farm. You can do so simultaneously but don’t run the configuration wizard yet.
  • Ensure you restart all servers in the farm, after patch is installed.
  • Now run Configuration wizard first on Server hosting the CA site. Wait until it completes.
  • If wizard fails, try to fix the issue.
  • Run the configuration wizard on the next server in the farm, wait until it completes and repeat the same action on remaining servers.
  • After patching is done, verify the BUILD version if there is going to be a version number change.

2.Would there be any risk/ challenges during updating patch?

  • Config wizard may run for longer duration at step 9 as it can take some time for that step to process, especially if your content databases are large. There should not be any issue as long as it is progressing.
  • Config wizard may fail. Re-run it through CA once and if that too fails, try using ps command.

3.What are the precautions need to take before patching Security update?

  • It is always recommended to test the patch in test environment before doing the same on PROD. I hope you had already completed in QA & that should tell you about the discrepancies if any.
  • You can also work with your Database team to secure CDB backups before you install the patches and later you can restore them to the point when you took the backup should the patch installation fail.
