Migration machine has a different code page than the Groupwise server. For example, the clients' mailboxes in Groupwise have a code page of 'US English' and the migration server is 'UK English'.
The requirement is for the UK code page in the target organization.
Is this going to create a problem?
As per the ReleaseNotes.htm:
- On the admin's workstation (the migration machine):
Must be a machine where the code page associated with the runtime locale is identical to the encoding for each mailbox being migrated. The Groupwise APIs used to retrieve the data do not support retrieval of data from outside the current code page. For example, if the migration server were configured on a German machine (using code page 1252) and used to migrate a mailbox containing Polish data (using code page 1250), data would be lost during the migration.
