Space requirements for the Migration Utility
Before you start the migration, ensure that your system meets the space
requirements for the following files:
!
Space for the migration log files—approximately 250 kbytes.
!
Space for the migration BCP files—these files contain the data and can be
very large. (The size of these files depends on the number and size of the
existing transactions. The size is usually estimated at 8 Mbytes per 1000
transactions.)
!
Space for the attachment files—the same amount of space as is currently
used by the attachments.
Note: The required space does not need to exist on the server in question as long
as it is accessible using a share. However, if you are using a shared location to
store the data it may slow down the migration process.
