No, what makes you think that? Just move your kit and applications across to TTS-CE (aka TTN V3)
Who told you only run 1 app? - I know some ‘public’ trial offerings only allow limited use (Loriot with 1 GW comes to mind - poss also the SMTC LoRaServer dev env.?) but no such constraints on TTN - infact the more GW’s you deploy the better! Then even with the constrained services you can always set up alternate accounts Note on TTN the only significant constraints are observe the FUP (max 30sec downlink airtime per node per day, max 10 downlinks, dont use a SCPF or DCPF (not a problem in your case…) and GW must be open to all - so do not attempt to block/blacklist other peoples nodes.
No reason for that - crack on and expand activity not stop it!
Ok, if you do walk away just ship it to me! I will find a good community use for it
Follow the docs (and use Forum Search top right of page) to migrate your gw - note you need f/w version 1.08 if poss (if online on V2 and updates allowed it should have updated to that anyway, or atleast use 1.07…if not at that level and still connected on V2 just set it to allow updates and it should pull over the network within approx 24hrs. Note no EUI is needed for registering a TTGW (Kickstarter) compared to process for other GW’s… go for it!
