If I transfer my tasks between instances, can & do they retain their identifiers?

Take Login – Nextcloud as an example — if I transfer it to a different instance of Nextcloud, shall it retain its 3de72895-d345-4ac4-8eec-1418e857ba7e/tasks/ACC3048D-8BA2-40A0-B1D3-C6763387872E identifier? Considering it’s a (G/U)UID, I fail to see why it wouldn’t be embedded in any export (and thus consumed by the importer) but I want to confirm.

I ask because I’ve many URIs to my tasks across the internet, and consequently need to be able to continue to reference my tasks regardless of where I happen to subsequently transfer them to and from.
