Know if you can migrate quarantined emails from IMSS 7.0 and 7.1 to versions 7.1 and 7.5.
No, it is impossible to directly move the quarantined files from version 7.0 or 7.1 to version 7.1 or 7.5.
To quarantine the mails in IMSS 7.1 or 7.5, the mails should be reprocessed. You need to copy the .AF and .DF files to the queue or reprocess folder. IMSS 7.1 or 7.5 will process the files with the current policy and imply the actions accordingly.
