Any company merger situation will require email systems to merge. One email system will typically remain, with the other being merged into it. Email mergers can be complex, with tight legal deadlines.
Migrating to Office 365 Exchange Online is our most common scenario. Customers are often moving off a hosted platform, Exchange On-Premise, Google G-Suite, Lotus Domino, or GroupWise.
Our team are often hired to support an existing email migration project, to provide expert email support during the migration and coexistence periods. Use our expert email migration services.
To succeed in a complex email migration project, you need an expert who has performed multiple similar email migrations.
The team here at emailmigrations.com have completed many different types of email migrations. Exchange to Office 365, Google to Office 365, Exchange Hybrid, GroupWise to Office 365, Lotus Notes to Office 365, hosted to Office 365.
We can cover all regions, with a mix of onsite and remote work.
Being able to migrate over a longer period, will require the old and new email systems to work together – this is called coexistence. Typically this will allow for mail flow, calendar free/busy, and a common address book. Users on both the old and new email systems will be able to keep working while the email migration progresses. Email coexistence during an email migration project lowers the risk of unexpected issues impacting everyone at the same time.
