Best Way for downgrading an appliance in version 9.4.x
Hello,
I will have a new mission on my F5 LTM 6900 which, today, is in version 10.2.0 (clean installation).
We have to downgrade this unit with the version 9.4.8 for a few time.
So I just want to be sure of the way to do that :
1) Backup the configuration in an UCS file
2) revert the LVM of Version 10 and use disk partition scheme
(SOL9745) => this solution create two partition HD1.1 and HD1.2 and one of this will keep the version 10.
But this solution have some troubles :
- if version 10.x is installed on HD1.1 partition, install of version 9.4 software may fail => (sol11283)
- if we revert the LVM with version 10.1.0, there must be a bootloader corrupt => (sol 11063)
So we have to use version 10.2.0 or later for reverting LVM and using disk partition scheme and we have to use HD1.2 for installing version 10.2.0 software.
image2disk --instslot=HD1.2 --format=partitions BIGIP-10.2.0.iso
But with version 9.4.x we may have MOS disappeared in the grub Menu.
3) downgrade and make a clean installation on the second partition HD1.1 => SOL9447 display all the method :
- Network Boot (or through a PXE Server)
- USB CD-ROM => SOL9589
- Local Installation
- Remote Installation
4) choose the version 9 at the boot :
switchboot -b HD1.1
- About the UCS file we have created in the first step, can we use it on version 9 ? I think not but not sure..
- About the licensing, if we downgrade on version 9 (with a version 10 on the other partition) we have to re-activate the license on version 9 ? And if we choose in few days to use the version 10 (we will probably make a clean install), the same license can be used and re-activate ?
Thank you very much for your reply.
