NimbostratusCSS Config to F5 Config
I don't know if this is the right section to place this question, if not please direct me to right place.
We have bought 2 F5 3600s, we migrating from old CSS to F5s now. i was wondering if there's tool or any script to convert the exiting CSS configuration file to F5's bigip config file. We are going to use the same ip address from CSS.
Any help would be greatly appreciated.

Hi,
What I have found is that there is no single tool that can accurately script a conversion of every possible configuration out there. There are so many variations in network topology, naming conventions, etc. that properly converting all the behavior of previous technologies is difficult.
If you have less than 50 or so virtual servers, you'll be better off doing the conversion by hand. If you have more than that, then a script can save time, but I'd still be prepared to do a fair amount of manual tweaking. I wrote a script to convert ~1600 virtuals from a CSM (not CSS) configuration, and it was highly dependent on known elements of the customer's config to work properly (so it can't be reused for another site), and even then I had to manually redo stuff.
Given enough time, a script could probably be developed to handle generic configs, but again it's usually not worth the effort for typically sized configs.

I wrote a perl script to do this when I converted my configs a few years back, let me dig for a little while... 
Allim_63326Well thank you so much for your quick response. I will wait for the script, we have close to 100 servers that I need to configure manually If I decide to that route.
Again thank u for the help- JRahmSorry to keep you waiting...I have a thumb drive I can't find and I'm pretty sure it's on there.
- Allim_63326Just wondering if you had any luck to find the script. Appreciate any help
- If someone posts an example of what needs to be converted, I'll see if I can build a little app that will either spit out the bigip.conf configuration or write an iControl app that will create the objects remotely.

- Guys
Sorry I am late to this. I wrote a CSS config conversion script in Perl. Contact me if you need it. j.alam@f5.com
The script is pretty extensive I could not attach it to this Post.
I will try posting it elsewhere on devcentral.
John - JRahmIt is now available in the wiki. Thanks John!
