A method, computer program product, and system for maintaining referential integrity is described. A method may comprise migrating a migration document in a migration shard from a first location to a second location. The method may further comprise adding a first location identifier associated with the first location of the migration document to metadata associated with the migration shard. The method may also comprise adding a second location identifier associated with the second location of the migration document to the metadata associated with the migration shard. The method may additionally comprise adding one or more shard identifiers to the metadata associated with the migration shard, each of the one or more shard identifiers corresponding to a shard that includes a document that may be referenced by one or more documents in the migration shard.

Maintaining referential integrity

A method, computer program product, and system for determining release differences is described. A method may comprise determining a first difference, the first difference corresponding to one or more activities that were at least one of: added to a main branch between a first release branch and a second release branch, and removed from the main branch between the first release branch and the second release branch. The method may further comprise determining a second difference, the second difference corresponding to one or more activities that were at least one of: added to the first release branch, and removed from the first release branch. The method may additionally comprise determining a third difference, the third difference corresponding to one or more activities that were at least one of: added to the second release branch, and removed from the second release branch. A delta activity set may be determined.
