Why are my folders truncated during migration to Google?
We migrate data to Google using IMAP. Both IMAP and Google's web interface has a label limit of 40 characters. If your Source folder structure contains more than 40 characters, we will truncate some characters to ensure that the labels are created properly.
When calculating a folder length, each subfolder is considered a character in Google. For example, a folder structure of A/B is 3 characters in Google.
