Our team of highly experienced Microsoft engineers can perform several different types of Email Migrations embedded with Email Consultancy services.  This is perfect for existing businesses wishing to move to Office 365 technology, migrating to later versions of Exchange as well as migrating from Office 365 to on-premise:   
 
Migrating from an On-premise Mail Server to Office 365 (Exchange Online) 

Migrating from an On-premise Email Server (typically a Microsoft Exchange Server) is the most common type of migration which we perform.   
In order to achieve this, one of our consultants will review your current infrastructure to establish the best method to migrate.   
Establishing the best method to perform the migration is based upon the complexity and several factors which include the quantity of mailboxes and mail enabled objects being migrated, whether there are public folders, multiple databases, DAG, and Domains being used as well as the mail server architecture.  Our Consultants will also provide you with some feedback on your current configuration with possible improvements or suggestions. 
 
Migrating from on-premise Mail Server to new Database/Failover 

In our experience, performing a migration from an on-premise mail server to new databases generally is triggered as a result of recommendation or an outage/disaster. 
It is good practise for businesses when using an on-premise mail server to use more than 1 Database for the benefit of not only evening the load but also can be used for Resiliency failover. 
 
Migrating Email from on-premise Mail Server and upgrading to a newer version of the Mail Server 

Should you be running an old version of Exchange and want to either upgrade straight to Exchange 2019 (latest version) or just upgrade from an older version to a newer version (e.g 2013 to 2016), this is something which Proxar IT Consulting can do 
 
Below is a table showing direct upgrades / Coexistence:

Migrating from Office 365 (Exchange Online) to a new Office 365 Tenant (Exchange Online) 

If you need to migrate Email from one Office 365 Tenant to another for reasons such as a merger or a split, or a change of company name, our Email Migration team can schedule, project manage and perform providing excellent comms, timelines and downtime working with you at a convenient time for your business –  we are also able to provide consulting and advice on how to achieve this. 
 
Migrating from Exchange Online to On-premise Exchange Server 

When using Exchange Online, you may have found that some of the features which you had available when using on-premise Exchange are no longer available, therefore you may have decided to move back to an on-premise environment.  Proxar IT Consulting can perform an Exchange Online to on-premise Email migration including setting up the on-premise Exchange Server should you have previously decommissioned, or never had one.  Our Email Migration team have many years’ experience with all the different versions of Microsoft Exchange
