I am working in an environment where the sharepoint patches are in the below level.
SP2013:
- Farm 1 - Build Version 15.0.4727.1000 - June 9th, 2015
- Farm 2 - Build Version 15.0.4535.1000 - August 2013 CU.
SP2010:
- Farm 3 - Build Version 14.0.7105.5000 - MS13-067 (Security) Aug 2013
- Farm 4 - Build Version 14.0.6029.1000 - SP2010 Service Pack1.
Now I need to install the recent updates on each farm as per MS recommendation for better performance of the servers. As the patch levels are very old, I am confused on planning the patch installation. Can i install the recent update directly or do I need to install any specific updates first and then install the recent CU? Please suggest.
