Aaron,

 

you mentioned using a partition installation for 10.x and 'keep the 9.x instance'. Is that really possible? I have done the upgrade using partitions and it seems that it will always wipe out any version 9 system that exists on the box.

 

 

of course there is an option to reinstall v9 AFTER the v10 system has been installed/upgrade.

 

 

If there is an install path that retains the v9 system intact, could you please share it (and share it with the F5 support peoples). This has been a fairly signficant issue here as I don't have 'spare' F5 appliances sitting around to work with this. I also need a good, reliable .. and quick method to fall back to v9 if that becomes necessary for my standalone systems (not HA pairs).

 

 

I think I have to rewrite my iRules that reference the classes. The update didn't seem to change/update the format of the class tables that were defined in the configuration. I was somewhat suprised. while the matchclass and findclass commands are supposed to continue to work (right?), it doesn't sound like other functions such as 'lindex' will return the correct value any longer. I'm thinking i should simply move to the 'class' command to be sure.

 

 

But information on what the transition capabilties are would cetainly be useful!

 

 

Thanks for your help and insight on this.
