Migrating large items/attachments

We do not impose any limit on item/attachment sizes. However, it is possible for large items/attachments to fail to migrate because of external factors.  There are two considerations:​

  1. What is the maximum attachment size allowed by the Destination system? 
    • Most email systems impose size limits. For example, if the Destination system has a 30MB limit, any item/attachment larger than 30MB will fail to migrate.
  2. What is the connection timeout for the Source and Destination system? 
    • ​​For security reasons, most email systems close opened connections after a predetermined amount of time. For example, if the Destination system only has 512Kbps of network bandwidth and closes connections after 30 seconds, we may be unable to transfer large items/attachments before the connection is closed.
