Equipment

Most intelligent creatures and NPCs in Starfinder carry tech gear. You should consider upgrading the armor and weapons wielded by such creatures in Pathfinder to their Starfinder equivalents. While the weapons could use the same statistics, applying the analog or tech trait makes it usable with the weapon grade system rather than needing compatible runes to upgrade. There are also spells and feats, such as Combat Hack, that only work if enemies have modern tech equipment. Note that while most people in the Pact Worlds carry a computer in the form of a comm unit or datapad, all tech armor has an integrated comm unit that makes carrying an additional communication device superfluous (but not unheard of). Giving a Pathfinder creature a gun is also an easy way to apply a simple but effective ranged attack if the creature didn't already have one—the image of a troll with a machine gun will stick with your players. Including tech gear in enemy stat blocks also gives the PCs ammunition (and batteries) to loot after the combat.

The integrated trait allows for equipment that players can't easily reuse in the midst of a series of encounters, although depending on the nature of the weapon and its integration with the creature, it might be salvageable with the Scavenger feat. In many cases, even the Scavenger feat isn't enough to allow a character to loot an integrated piece of gear, such as an integrated jetpack that uses a firebreathing creature's internal flames to keep it aloft.
