- hooleylistCirrostratusYou cannot load a 4.5.x config directly on 9.x. Depending on the size/complexity of your 4.5.x configuration it might be cleaner and faster to build the 9.x configuration from scratch. There have been a few significant changes in logic between 4.x and 9.4.x, so even if you go through the upgrades described below, you'd need to verify the configuration is accurate. Also, moving a UCS from one platform to another isn't officially supported and would require a close review of the config.
- js55161_47239NimbostratusMy mistake our 4.5 is on 540's also i have 9.0.5 on 3400. I assume i can copy the ucs file directly from 9.0.5 to the new 9.4.3? I think i have to change the hostname on the destination device first and then copy the ucs file across, reboot and then change the hostname back?
- hooleylistCirrostratusI think it was only in 9.4.2/9.4.3 that installing an older UCS was supported. I don't think it would be good to try installing a 9.0.x UCS on a 9.4.3 unit even if they were from the same platform. The format of the bigip.conf and bigip_base.conf files have change significantly between those versions. Also, if you're taking a UCS from a 540 platform and trying to install it on a 6400, I expect you will get errors about interfaces not being defined correctly in the bigip_base.conf as the physical ports and port numbers are different.
- Deb_Allen_18Historic F5 AccountF5'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))
- rao_26276NimbostratusHi
- Sandro_Martins_NimbostratusHi I am a newbie with F5 and I need to upgrade from version 4.5 to 9.2.5. I saw the comments good suggestions on this thread, but I am actually looking for a doc/guidelines on how to do this upgrade end-to-end. If not end-to-end at least the main steps to follow so I have something to guide me.
- dennypayneEmployeeThe link that hoolio provided earlier (Click here) is probably the best documentation on the process.
