    A lot of manual work sadly - There's no "easy way" to my knowledge.

     

    I'd be tempted if possible to get all the software of the present devices onto version 10.2.4 - Which will give you at least consistency between version 10 software.

     

    Depending on hardware after that - I'd then be tempted to take them up to version 11.5.3

     

    From there you should have a decent base to proceed.

     

    You will need to review your iRules for deprecated functions

    Hi Iain, Thanks for your suggestion! I have tried to find out ways but I am getting stuck due to challanges. Yes, I do see a lot of manual task as well. So I thought to have some idea from you guys.

     

    I have control to the new box which is having 11.5.3. I don't have control to present three box having 10.2.3, 10.2.4 and 9.4.5 only I do have the config files in text format.

     

    I can downgrade the new box to 10.2.4. Now the question is if I brieng the new box to 10.2.4, will that support config lines of 9.4.5?? I am not sure...

     

    Thanks, Nantu

    Nantu, there is no way to merge all three different software version's bigip.conf to one v11.5. Only option to take manual work.

    You may be able to take the new box to 10.2.4 - You'd have to check the F5 Hardware/Software compatibility matrix.

     

    The good news though - Version 10 supports Bigpipe aswell as TMSH... So..

     

    You can enter lines of config using the bash shell - For example

     

    b virtual 'myreallygoodvirtualserver_vip destination 10.10.10.10:80 profile myprofile '

     

    etc etc

     

    That would be a lot quicker... All depends how complex your VLAN configuration/lockdowns were off the old boxes of course if they were tied to interfaces.
