wenn mich nicht alles täuscht kannste das per Adminkonsole in einem Rutsch pro Server (!!!) erledigen:
load convert -r mailverzeichnis\*.nsf * schablone.ntf
(schau mal in Admin Help und suche nach convert:
zB:
load convert [-r | -l | -f | -m | -e | -u | -s] mailfilepath existingtemplatename newtemplatefilename
where -r converts mail files in subdirectories of the specified directory, -l creates a text list of mail files, -f uses a text list of mail databases to determine which mail files to upgrade, -m converts the file or files for IMAP use in Notes 5, -e converts the file or files for IMAP use in Notes 6, -u converts all custom folders to the Inbox design, and -s upgrades folders created without the Preserve bit set. Mailfilepath specifies which mail file or files to upgrade, existingtemplatename specifies a certain mail file design (for example, only mail files using Notes 5 design) to upgrade, and newtemplatefilename specifies the template with which to upgrade the mail files.)
