Hey guys,

I always impressed by the community responses. Thanks.
So ok l need to do in stages. Where can l check RootROM compatibility matrix? l know usually we don't touch or upgrade it but l just wanted to check what is the minimum version required in order to run 15.X

Thanks,
Mykhaylo

Hi Mykhaylo,
Here's the complete compatibility matrix:

Your X250 will run fine with BootROM 1.0.3.5. However, the latest is 1.0.5.7. It can be provided by GTAC, but isn't required to upgrade.

Hello Mykhaylo,

I believe the following article will be able to anwser your question:

https://gtacknowledge.extremenetworks.com/articles/Q_A/Upgrade-from-12-X-to-15-X/

however in short no you will need to upgrade to 12.5.x first then go to 15.
