We import transcript data from our legacy system. I don’t recall the exact number, but it was a large amount of data. We broke the imports to 500-1000 records at a time incase we had issues. Took a while with that amount but seemed easier to manage. No errors other than not flagging the credit type correctly sometimes in the import file. We communicated to learners to use the email we had on file and shared the email and the biggest problem we had was users not using the email we imported the record with, so their data didn’t match to their profile. At the time, the import tool didn’t have the option to assign records immediately which involved a few extra steps to resolve. Have not experienced issues due to the amount of data imported.
