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
