actualy they are both doing the same and i suggest you to use the first one because there is no use in an "if"....

I'd try with "Unit-type of (Triggering unit) equal to ..."...

sorry if i wasn't clear enough, there is a different between what is called "research" and "upgrade", i can not refer to an upgrade with the tech condition nor with if/then/else nor with "triggering unit {and i really tryed any possible combination iwth it). how do i refer to the upgrade? upgrade - like when the keep is upgraded into a castle, etc.
Edit:
NVM fellows, some combination of triggering unit does work. thank you all who help.

just to clear it for you when you upgrade a unit it stays the same specific unit and only changes it's type of unit
