Migrating v4.5 config to v9.4.3 BIG-IP

i am currently upgrading our BIG-IP's from v4.5 (3400) to v9.4.3 (6400). I need some advise on how to get the config from the v4.5 devices onto the new v9.4.3 devices. I have backed up the config file...

F5's best practice recommendation for 4.x to 9.x migration is to perform a full 4.x configuration audit, then rebuild the config by hand to take advantage of LTM features. However, you could re-image the target device with 9.0.x, copy the 4.x ucs to the target device and use the OTCU (One Time Conversion Utility) to convert the configuration, then upgrade the target device again to 9.4.3. The OTCU may not exactly replicate your existing configuration, but it will get you fairly close with very little work. (For a good example of a manual intervention you may have to make after the conversion, see my last tech tip (Click here))

 

 

To roll the 9.0.5 config forward to 9.4.3 without rebuilding manually, you could take the same approach: Re-image the target box to 9.0.5, apply the UCS, then upgrade to 9.4.3.
