bigpipe to tmsh script

Its been years since worked on v9. But if my memory serves right, you can't directly upgrade from v9 to v11 or v12 directly. You would need to first goto v10.x. And from v10.x you can jump to v11 or v12.

Because v10.2.x started supporting both tmsh and native bigpipe commands. Also I dont think you'd need to convert your conf file here.

Install the 10.2.4 image in the separate volume., load the UCS on the new volume and see the config file.

And from there you can goto next version. Have v11 in 3 volume installed. Let us know how it goes.

Incase of issues, you can still rollback to your original volume.

Edit: You might see some monitor (CF/LF), irule syntax issues post upgrading. Thats expected. Which is required to be fixed manually.
