How do I downgrade objectID from 64bit to 32bit?

[BrandonGuo]

I am trying to share a table with SYNC enabled, but the table's objectID was created with 64bit ObjectID. How do I downgrade the ObjectID?

I tried "export features" , and "import feature class"; neither of them allowed me to change the objectID data type.

There's a geoprocessing tool to upgrade the objectID to 64bit, but no downgrade tool.

I understood that the move to 64-bit object IDs was obligatory when we upgraded our database to Utility Networks version 7 (ArcGIS Enterprise 11.5 and Pro 3.5.5). When will 64-bit object IDs be fully supported?
