Challenge Faced: A seamless transition from SourceOne to MailMeter
A UK-based hospital faced the challenge of migrating from SourceOne to ComplyKEY MailMeter. They wanted a seamless transition while ensuring data integrity and compliance. This case study outlines the migration process, the tools used, and the challenges met during the transition.
Migration Process
- Install MailMeter
- Set up Transvault for SourceOne Discovery
- Migrate data from SourceOne to MailMeter
- Restore SourceOne shortcuts
MailMeter Installation
The client opted for a dual-server MailMeter setup – a Live server for capturing new emails and holding data from Jan 2021 onwards, and a Legacy server for archiving emails from 2020 back to 2009. MailMeter servers were configured to capture all emails sent and received by users.
Transvault Installation
Transvault, is our chosen migration tool. The Transvault system requires an SQL Server and one or more Transvault Migrator servers. In this case, it was decided that three Transvault Migrator servers were needed to migrate all the data on time, which was estimated to be between 12 – 18 months
SourceOne Discovery
Next a discovery process is conducted on the SourceOne system. Transvault calls this the ‘Gather’ process. It runs on the SourceOne system and discovers and records all the metadata from SourceOne for each message, it records the:
- SourceOne message ID
- The message
- The attachment
- The location of the message in the filestore
Migration used a ‘journal’ approach, transferring data in monthly increments to MailMeter. Each MailMeter server was equipped with a 1TB drive for SourceOne messages, accommodating 2-3 months of data. Transvault migrated messages from SourceOne to MailMeter, converting them to Microsoft Exchange standard message format (EML). Calendar entries, constituting around 10% of the total data, were migrated to PST due to format constraints.
SourceOne Migration of Messages to MailMeter
The migration process displayed impressive performance, with up to 2 million messages migrated daily exceeding first predictions of 1-1.25 million per day. Transvault maintained a ‘Chain of Custody,’ recording the message transition for potential legal requirements.
