@Martin thank you for the suggestion, we are not licensed for that unfortunately so we might need to do something else at least for the time being.
@RMG I am leaning slightly using a dedicated SFTP client to transfer the files, I am concerned managing a lot of remote transfers via scheduled services in the ESB could be a bit tricky. Has anybody tried it this way who can put my mind at rest? Is a combination of IS admin and MWS sufficient to deal with any file transfer failures etc?
Thanks
Ed
