Upgrade/Downgrade Path for Virtual Form Factor in FIPS Mode

When upgrading from 6.1.x or 5.6.x to 6.2.x or later images of virtual form factor (VFF), there may be a disruption of service links, stats/logs connections, and remote sessions in FIPS mode. This issue is observed only when the VFF in FIPS mode is upgraded to 6.2.1 or later.
Upgrade or Downgrade Versions
Follow the below steps if you are on a VFF pre-6.2.1 with FIPS mode enabled and upgrading to software version greater than or equal to 6.2.1 (includes 6.2.2, 6.3.4, 6.3.5 and 6.4.1), (excluding 6.2.3, 6.3.1, 6.3.2, 6.3.3 already blocked on the Controller).
  1. First, disable FIPS mode on VFF.
  2. Upgrade to the desired software version.
  3. Then, enable FIPS mode. Enabling FIPS mode can take up to 20 minutes.
The above steps do not apply when upgrading directly from 6.1.x to 6.4.2 or higher.
Considering these known limitations and FIPS certified versions are 6.1.2 and 6.4.2 or higher, for VFF in FIPS mode on any older software version (< 6.2.1), Palo Alto Networks recommend the upgrade path to be 6.4.2 and all later versions.
