Hi,

Only complementing the information presented above:

If you will Install New Software Images or Hotfixes

Determine version to install
Ensure license service check date is up-to-date
Download software image files and release notes
Read release notes and follow specific upgrade directions!
Import software image files to BIG-IP (iso, md5) Note: Upgrade standby device first
Verify integrity of software image (md5sum -- check)
Install software image to inactive boot location
Activate boot location
Test!

If you will Implement Configuration Changes During a Maintenance Window

Create "before" UCS archive
Run staged tmsh script with configuration changes
Test!
If successful, create "after" UCS archive
If unsuccessful, restore from "before" UCS archive

Note: The install/upgrade time (typical: 30 to 120 minutes per cluster) depends on several factors including the platform used, provisioning, connectivity to download and upload the images, testing time, troubleshoot, etc... If you got the chance to deploy Enterprise Manager VE or BIG-IQ Device, definitely you will improve the all process. The outage would be minimal (typical: less than 30 seconds) because you switch/failover between devices throughout the process.
