SFB Update CU 11 HF1 Update procedure

Question

We are planning to update from CU 10 to CU 11 HF1. can we install CU11 HF1 directly or should we install the intermediate update one by one.

1. We have 2 sites with standard front pool in each site and edge server in each site

Site1
PRStandard FE
Edge

Site 2
DRStandard FE
Edge

DRFE is configured as Backup pool FQDN when your get-cspool.

Please advice
a. order of patching the servers

The DC and DR site front end servers are pool paired.
Can we patch DR site servers (FE & Edge). Get downtime for DC site servers (FE and Edge). We dont want to failover to DR site once they are patched. We have a complete downtime.

Cheers
Priya

Hi @Priya Jayaraman

We recommend you patch each site one by one. Work with one pool and one server at a time when patching and never patch more than one front end server at one time. For more details about it, you can refer to:
