Compatibility concerns

Gmail and IMAP handle email organization differently. Before you start the migration, it is important to understand these differences so you know what may change and what may need adjustment before the migration.

Labels and folders

Gmail organizes messages using labels, and a single email can have multiple labels. IMAP uses folders, where each message can belong to only one folder.

VaultMe for Admins does not duplicate messages; instead, it uses its own internal prioritization rules to determine the most suitable destination folder for each message during the migration.

For example, if a message in Gmail has both the Inbox label and a custom label, the message will be placed in the corresponding custom folder in IMAP and will not appear in the Inbox.

This approach helps avoid inflating the size of the destination mailbox and the confusion caused by multiple copies of the same email message.

To avoid these changes, users can reorganize emails with multiple labels in Gmail before the migration so that each email message has only one label.
