Bigip Restoration From Hardware to VM

Hello Sankar_Ganesh​ 

I found some information that could help answer your question on our myf5 portal.

According to the Article

K9420: Installing UCS files containing encrypted passwords or passphrases (11.5.x and later)

 https://my.f5.com/manage/s/article/K9420

The issue appears to be that you have passwords in the configuration file. to resolve the issue, please enter the crypto passcode or, you can also copy the master key from the r2600 tenant

Obtain the password or passphrase used to reset the master key.
Log in to tmsh by typing the following command:
tmsh

Reset the master key by typing the following command:
modify sys crypto master-key prompt-for-password

At the password prompt, enter the master key password or passphrase.
Secure copy the UCS file to the /var/local/ucs directory of the BIG-IP system. For information about transferring files, refer to K175: Transferring files to or from an F5 system.
Load the UCS by using the following command syntax:
load sys ucs <ucs_archive_name>

Save the BIG-IP configuration by typing the following command:
save sys config

or

f5mku -K

The command output appears similar to the following example:

oruIVCHfmVBnwGaSR/+MAA==

Copy the output.
Note: The output is the master key that you will install on the RMA BIG-IP system.

Log in to the RMA BIG-IP system command line.
Install the master key that you copied in step 3 to the RMA BIG-IP system using the following command syntax:
f5mku -r <key_value>

For example:

f5mku -r oruIVCHfmVBnwGaSR/+MAA==

Verify that the master key is the same on the active peer BIG-IP system and the RMA BIG-IP system by typing the following command from the command lines of both systems:
f5mku -K

save the config using the command below

tmsh save sys config

Restore the UCS file to the RMA BIG-IP system using the following command syntax:
tmsh load sys ucs <file_name>.ucs no-license

I hope this helps
