Known Affected Releases

6.4.0 6.5.0 6.6.0 6.7.0

Description (partial)

In 6.4.0/6.5.0/6.6.0, the management access to data-interface(outside ) is configured with HTTPS and the same interface(outside) is configured as outside interface in RAVPN. Both are running on 443. The issue occurred due to the invalid configuration allowed in 6.4.0/6.5.0/6.6.0. The upgrade should work after removing management access to the outside interface.

Upgrade will fail if the device configured with the same port number in RAVPN outside interface and  management access port number of the interface. 

1. Install FDM on 6.4.0 or 6.5.0 or 6.6.0
2. Configure RAVPN profile with outside interface as any data-interface.
3. Configure management HTTPS access to the above data-interface and deploy the configuration
3. Upgrade to 6.7.0
