[Archivesspace_Users_Group] ArchivesSpace API questions

Hi all,

I've been working on a project to remigrate our original database from Archon to ArchivesSpace due to some top container issues in the first migration we ran. After our initial migration, changes were made in ArchivesSpace and those changes would not be present in the new migration. In an attempt to merge the changes from our old ASpace db to the new one, I've been working with the ArchivesSpace API via ArchivesSnake to pull JSON copies of any record that was modified after the original migration. My goal is to import these modified records to the newly migrated db, but I seem to have run into a problem.

After remigrating, it looks like the IDs of records have changed so it isn't as easy as deleting the unmodified record from the new migration and importing the modified JSON because their IDs do not match up. From what I saw in the ArchivesSnake and ASpace API docs, it appears that the only way to refer to a record is with that ID. Are there any other ways I can compare records through the API or am I stuck using the ID?

The only way I have been able to compare records to each other and find the new ID of the modified record is to iterate over all records in a specific category for each and every one of the records I am attempting to upload. This takes an incredibly long time. Theoretically I think I can load all IDs and records into local memory to iterate over rather than querying the ASpace API and this should speed up the process but I was wondering if anyone knew of a better way to accomplish this such as using EAD ID rather than ID through the API.

Thank you,
