Steps to move the complete configurtion from one LTM A to LTM B

Hello All,

We are working on the project of replacing the LTM with a new LTM with an option of one on one replacement.

 

Could you please help me to know the steps for the complete copy of the configuration ( All objects, slef IP, floating IP, Certs, Keys) from LTM-A to LTM-B?

 

Is there any option to compare the config of LTM-A with LTM-B to ensure we have not missed any configuration?

 

Thanks a lot in advance.

 

Regards,

Thiyagu

    Hi Thiyagu,

    You can backup in LTM-A and restore configuration in LTM-B

    For LTM-A:

    1. Backup UCS

    save /sys ucs /var/local/UCS/MyUCS.ucs no-private-key

    2. Download UCS

    3. Look f5mku

    f5mku -K

    For LTM-B:

    1. Upload UCS to /var/local/ucs folder

    If the interface numbering of the devices is the same, skip to step 8.

    2. Create temp folder in /var/local/ucs

    cd /var/local/ucs
mkdir abc
cd abc

    3. Unzip UCS

    tar -xzf /var/local/ucs/MyUCS.ucs

    4. Open bigip_base.conf folder

    nano config/bigip_base.conf
# or
vi config/bigip_base.conf

    5. Change all interface names in bigip_base.conf

    1.1 > 1.0
1.2 > 2.0
1.3 > 3.0
...

    6. Save bigip_base.conf

    7. Zip files

    tar -czf /var/local/ucs/newMyUCS.ucs *

    8. Enter LTM-A's f5mku value

    f5mku -r <ltm-a f5mku value>

    9. Restore UCS

    tmsh
load sys ucs newMyUCS.ucs no-license no-platform-check

      Hi EAA,

      Thanks a lot for your reply. I have couple of more questions on restoring the UCS config in the new LTM.

      ​

      1- In.a scenario wherein the LTM has many partitions then in this case do I need to edit the "bigip_base.conf " file of all partitions ?

      2- on renaming the interface in the bigip_base.com file, since the new LTM is a high end device I'm finding lot of interfaces in the new LTM,

      Do I need to remove the additional interface configuration in the new LTM bigip_base.conf " file? and please confirm that I have to replace the interface number in the new LTM config file as like existing LTM base confi?

       

       

      Existing LTM:

      net interface 2.1 {

         if-index 864

       

      new LTM

      net interface 6.2 {

         if-index 560

         mac-address 00:94:a1:7d:e0:9e

         media-max 10000T-FD

         mtu 9198

       

      Thanks a lot in advance.

       

      Regards,

      Thiyagu
