Tag history sync

Hi all:

I have a Cloud Gateway Version 8 manages varius remote edge via EAM so we also sync the Edge historian and it works fine.
Now, my next step is to connect normal ignition gatewyas and have the same scenario with remote ignition gateways who has his local tag history and database.
My doubt now is how to have the same configuration on this cloud ignition gateway as the locals gateways via sync without use an splitter or there is no additional ways for it.

Our objective is to export this local database to cloud, keep the same sqlth_te with same tag_ids and via S&F have a complete sync of database. It is possible? Or what is the best architecture for this cases?

Thanks in advance,
