  9. Patch the following Application servers: SPAPP02, SPDCH02, and SPSRCH02 in parallel, and then restart the computers.
  10. With the front-end web server (SPWEB02) out of the Load balancer (See step 7), Open the SharePoint 2016 Management Shell, and then run following PSConfig command: PSConfig.exe -cmd upgrade -inplace b2b -wait -cmd applicationcontent -install -cmd installfeatures -cmd secureresources -cmd services -install

  2. On the front-end web server (SPWEB01) computer, run the PSConfig command from step 10.
  3. Add the front-end web server (SPWEB01) back into the Load balancer.
  4. On the Application server (SPAPP01), run the PSConfig command from Step 10.
