This section describes how to downgrade from 4.1, and includes the following topics:

If you configure the shared management VLAN feature that was introduced in 4.1(1), this feature is not 
supported when you downgrade to a pre-4.1(1) release.

See the following issues when you use this feature, and then downgrade:

The interface configuration for the shared VLAN is accepted in the first context configuration in 
which it appears, but is rejected in subsequent transparent mode contexts.

For these subsequent contexts, if the startup-config has the management VLAN configuration 
defined directly after another VLAN configuration for through traffic, then the name and security 
level associated with the (rejected) shared management VLAN is erroneously applied to the 
immediately preceding VLAN.

Workaround: Remove the interface configuration for the shared VLAN from all contexts before you 
downgrade.

For example, you have the following configuration in 4.1:

interface Vlan100

 bridge-group 5

interface Vlan101

 nameif dmz

 security-level 100

 management-only

 ip address 10.90.90.4 255.255.255.0 standby 10.90.90.5 

After downgrading, the shared management interface vlan101 command is rejected if it was already 
used in another context; so the nameif dmz and security-level 100 commands are applied to VLAN 100, 
overwriting the original nameif and security-level commands. (The VLAN 101 management-only and 
ip address commands are rejected because they are not allowed for the interface vlan command 
pre-4.1). The resulting VLAN 100 configuration is the following:

interface Vlan100

 bridge-group 5
