Unless they've made a special case for these weapons - which is highly unlikely - you'll lose the catalyst and/or forma on them.

Or more accurately, the catalyst/forma are deleted when you commit to build; the weapon you claim from the foundry is a fresh, unaltered weapon. It's not an upgrade so much as it's completely removing one weapon and adding another.

Again, unless they've made a special case for it.
