Migration time dependends on how many photos and videos you have as well as how many other migrations are going on simultaneously.
When you request a migration, we'll respond with an estimate. Please allow up to 72 business hours for your migration to begin.
We'll contact you at the end of the migration to let you know that it is complete, as well as any errors that occurred. You can then verify that all your files have been migrated to Eyefi Cloud.
