Lotus to Google Mail migration Utility Development

About the Client

The client provides technology solutions to increase organizational efficiency through Google Apps based cloud-computing solutions. The client owns several software products/ accelerators that simplify the adoption and transition of business applications within organizations to the Google Application suite. The client’s software products facilitate adoption of Google Mail, Google Docs and other Google business applications within organizations.

Business Challenge

As part of its service offering, the client facilitates e-mail migration from Lotus Notes to Google Mail to clients across the US and Canada. The client had a software application that automated the migration process; however there were limitations to the application and manual intervention was needed for fixing issues.

The client sought an offshore technology partner with expertise to build a more robust and reliable software application that automatically migrates the mail structures and attachments from Lotus NSF mail database  to the user’s Google mail account.

Having demonstrated proven expertise in Google Apps development, the client and Silicus entered into a partnership in which Silicus would provide implementation and migration services for the client’s end customers on an ongoing basis. The client also maintained a full time offshore development team to develop new software tools / accelerators and improve the features and performance of existing software.

Silicus supported the client in taking its e-mail migration services to end customers, and fixed any problems and issues that surface during the migration process. The process involved migrating mail structures and attachments from Lotus NSF mail database to the user’s Google mail account.
