Updating lots email addresses...how?

[Christopher Ramey]

Hello all!

 

I'm hoping I can get some help here.  I just started as an administrator here at a public school system and we need to update all the students email addresses.  They were created incorrectly by someone previously. 

 

I am new to Google Apps and found GAM and am thinking it should do the trick.  I just don't know how!

 

Here is what we need to do:

 

Old email: 12...@school.edu

New email: firstname...@school.edu.

 

We do have a csv with all the students names as well as the right email address, but I don't know how to upload/merge it into our current student suborgranization.

 

Thanks in advance for the help!

Mac, Linux or Windows, 

can you post a sample line form the csv?
