The Army intends to migrate all its email accounts to DISA Enterprise Email by the end of next March, with another half million Army Knowledge Online-only users set for migration in February.
"We are well on our way," said Michael Kreiger, Army deputy chief information officer/G-6, in a DISA statement.
The service estimates the DISA solution will result in cost avoidances between $76.1 million and $85.9 million annually through the next 5 years. That number is less than the $100 million annually the Army initially estimated, service officials acknowledged in a February report (.pdf) to Congress.
Migration to the DISA solution has been bumpy, with what Lt. Gen Susan Lawrence, the service CIO, termed "nasty stuff" halting the migration in summer 2011 and Congress mandating another pause in late 2011 that lasted through the first months of 2012.
Defense Department Chief Information Officer Teri Takai said in March that the Air Force has said it will also migrate its users to the DISA cloud.
