If you were upgrading from 3.9, there would be some requirements in terms of ROMMON version but, we can not see anything mentioning version 3.10, which means, you are good to go.

 Only observe the tacacs suggestions.

Follow these guidelines:

• Before upgrading to Cisco IOS XE Release 3.11.3aE, ensure the following:

  • Remove the tacacs-server command configuration using its no form.

  • Configure the TACACS Server using the new tacacs server command.

  • If the TACACS group server is configured using the server-private CLI, unconfigure the private server and configure a public server using the server name server-name command.

• If you are upgrading to Cisco IOS XE Release 3.9.xE and using Supervisor Engine 8L-E, you must upgrade to ROMMON 15.1(1r)SG6 before upgrading the IOS-XE image to 3.9.0E or newer versions.

• If you are upgrading to Cisco IOS XE Release 3.9.xE and plan to use VSS, you must upgrade your ROMMON to version 15.0(1r)SG10. Otherwise, you must upgrade your ROMMON to at least Version 15.0(1r)SG2.

• If you are upgrading to Cisco IOS XE Release 3.9.xE and using Supervisor Engine 7-E or 7L-E, we recommend that you use ROMMON version 15.0(1r)SG10 or a higher version (if available).

• If you are upgrading to Cisco IOS XE Release 3.9.xE and using Supervisor Engine 8-E, we recommend that you use ROMMON version 15.1(1r) SG5 or later version (if available).

• If dual supervisor engines are present, first upgrade your software to Cisco IOS XE 3.2.0SG or higher, then upgrade your ROMMON to version 15.0(1r)SG7 to avoid an uplinks issue (CSCtj54375).

• Do not perform a ROMMON upgrade and a system software (IOS) upgrade together, if it involves an RPR failover. After such an upgrade, one of the Supervisor’s interface configurations are lost (CSCvu66041).

  We recommend that you use an ISSU compatible IOS image for an IOS upgrade that is done along with a ROMMON upgrade. To display the ISSU compatibility matrix data between two software images on a given system, use the show issu comp-matrix stored command.

Hi,

The procedure to upgrade the 4500 series with sup-8 is pretty simple since you don't need to upgrade the Romon:

Make a copy of the config

Load the new IOS into the flash 

Validate the new IOS by running the MD5 command

Negate the old IOS from the boot variable (no boot system flash <old IOS>)

Add the new IOS to the boot variable (boot system flash <new IOS>)

Save the config

In a maintenance window, reload the chassis
