Hosted Exchange is a suitable solution for a small sized business which has a relatively lesser size of data to manage. It also protects the communication from any threat and the data is instantly accessible. However, when the size of the organization grows, they need to spend more to manage the hosted Exchange data, and the vendor has to remain on its toes to scale the increasing amount of data. In such a case, the on-premises becomes a natural choice for the business owner to migrate the data to the onsite environment. Here, you have the total authority over your data, and you don’t need to wait for the vendor to implement the desired change.
However, here comes the challenging part for any Exchange Administrator as there is no pre-defined method to migrate the hosted Exchange mailboxes to on-premises Exchange Server. So, the Administrator has to plan the strategy before starting the migration. Let’s start the step-by-step procedure –
Before going to the migration, you should evaluate the weightage that both on-premises and hosted exchange bring to your business. There is a table with the parameter that affect the usage, requirements, and benefits of both platforms –
|On-Premises Exchange||Hosted Exchange|
|Purchase Cost||You need to pay a single amount while purchasing the license.||You can pay the provider on a monthly or annual basis.|
|Maintenance Cost||The additional hardware and software cost are required along with the maintenance support from the IT Administrator.||He provider charges you as per your usage and subscription plan. You can also ask for any change in the environment flexibly.|
|Storage Cost||No additional storage is required once the hardware specification has met the requirement.||You need to ask your provider regarding upgrading the server size limits.|
|Deployment cost||A capital amount to required to deploy and create whole exchange environment.||You are dependent on your service provider that how quickly it can create the environment suitable for your business.|
|IT environment management cost||A dedicated IT team is required to constantly monitor and upgrade the server changes.||You require the minimal task needs to perform at your side as the provider will make sure of availability and security of data.|
|Scalable||Scaling up and down means changing the hardware and software resources.||You need to mention your requirement to the provider, and it will take of all the changes.|
|Administrative requirement||A well-established Exchange server environment will require only to take backup and upgrade based on your need.||You are dependent on the service provider and its team for all the administrative tasks.|
So, this was the whole procedure to migrating the mailbox data from the hosted Exchange to on-premises Exchange. It requires the Administrator to handle each mailbox manually and migrate its data in a PST format to the destination account. This procedure is not the official migration from Microsoft and is ready to face different errors and warnings at each step. This procedure may also leave the unbalanced data means the data from any another mailbox many reaches to a different mailbox. This procedure does not ensure data consistency as well as security.
