The TGID is actually the same: 2076 = 33216, as they are both 81C in HEX. The RRDB, scanners, and most software capable of tracking SmartZone systems don't display the TGID's in the same manner as the system itself, or CPS for that matter. You will not find "33216" anywhere in the SmartZone system controller or in CPS...instead the actual TGID of 2076 or 81C is used. This is because RRDB/scanners/software take the status bits into account, hence the x16 notation with the TGID.
In any event, the three DoITT systems are linked as they share the ASTRO 25 core and have SmartX site converters in place, so you may potentially see some talkgroups active on more than one system at the same time. Just remember to either divide the SmartZone TGID by 16 to get the P25 equivalent (aka the actual TGID), or look at the HEX values to match them up.
It appears that instead of reusing the old SmartZone TGID's, they are creating new blocks on the ASTRO 25 system as they did with Sanitation, Parks & Rec, DOT. No assumptions should be made regarding the fleetmap on the ASTRO 25 system, and that includes pulling talkgroups from the UHF or 800 SmartZone system to the ASTRO 25 system without first verifying usage (e.g. adding the "Snow Channel" to the ASTRO 25 system in the middle of August
