There's only one problem with the "universal upgrade" button. The best way to explain is by example:

I always use Temporal race tech, which eventually grants "Temporal Space Yards." HOWEVER, you can't just upgrade a normal space yard to a temporal yard, you have to scrap the old yard and build the new one (since they both build ships, you have to scrap one before building the other, even if there's space available on the planet). IN ADDITION, if you continue researching ship sizes and get the upgraded regular space yard, and then use the universal update, any old yards you haven't converted to temporal yards also get upgraded. If you're not paying attention, the system could end up spending your resources (and build time) on upgrading facilities that you're just going to scrap and replace.

The GOOD thing about the universal upgrade is that it also updates all the pending queues (i.e., if you have 15 Research Facility I's in a queue, and use the universal upgrade function, that queue is changed to read 15 Research Facility II's (or III's, if you researched that fast). Which brings up another issue - on long build queues, sometimes you'll research multiple upgrades before finishing a queue; you'll want to delete old upgrade orders when you issue the new upgrade order, especially since the new upgrade order cost was calculated based on the existing facility costs, not the "post-upgrade" cost. In other words, you can have "Upgrade to Research Facility II (x5)" followed by "Upgrade to Research Facility III (x5)" in the queue. The cost associated with the upgrade to RF III is based on upgrading RF I's to RF III's, not RF II's to RF III's. So that intermediate order (upgrading to RF II) is not only useless, it's a waste of time and resources.

Hope this all made sense - I'm just passing on the things I've noticed while playing, and it's much easier to understand when looking at the queues themselves...
