Will the entities, which were merged automatically/manually, retain the same entity ID after the entities are unmerged?
When two entities or profiles are merged in Reltio with Reltio ID/Entity ID, R1 (older profile) and R2 (newer profile), the merged profile will have the Reltio ID R1 of the older profile.
Note: When merging using API request, the entity id that will be a winner can be chosen using explicitWinner parameter
Should these two entities or profiles be unmerged, both the entities will have ids from before the merge.
Customers should make it a practice to try these requests in their lower environment always.
