Change Sage ID email, update Sysadmin email

SUGGESTED

I have a new email address so I would like to update my sage ID email.  I would also like to update the email associated with the sysadmin on multiple files.   I have seen posts where people have said the only way to change the sysadmin email is to send the file to sage support.  However, as I have multiple clients and files I would not want to have to send all the files into change.   Is there anyway to change the email?  I have attempted to "unshare" the files and to make copies of the files but have not been able to change the email.   Is there any process that sage has for when someone's email changes?
