Acquiring a company with it's own domain that is managed by another IT company. who manages the local domain.<br />
<br />
We are migrating Exchange mailboxes from local Exchange server and migrating up to Cloud based email. &nbsp;<br />
<br />
If we take a backup of the information store after migration, is any of that data accessible in the future, without the original exchange server, i.e. is there a way to mount the information store on a backup exchange server, etc. &nbsp;<br />
<br />
I am just trying to determine if there is any value in safe keeping of that data in the event we ever get audited, as it contains data and information from legacy or termed users. &nbsp;Also, if there is any value, I'd prefer to keep a copy of the exchange information store, and just mount it up in the event that we needed to. &nbsp;Otherwise, keep in stored away on some redundant array or cold disk storage.<br />
<br />
Any thoughts in regards to this appreciated.<br />
<br />
Thanks.

Microsoft Exchange Information Store

Microsoft server applications are those applications developed specifically, but not necessarily exclusively, on the Windows Server platform. In addition to well-known products like SQL Server, Exchange, Internet Information Services (IIS), Microsoft Dynamics, Forefront, Lync and Sharepoint, they include applications like Skype, BizTalk, Hyper-V, Groove and Commerce Server. Server applications are managed with the Microsoft System Center.

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Security is the protection of information systems from theft or damage to the hardware, the software, and the information on them, as well as from disruption or misdirection of the services they provide. The main goal of security is protecting assets, and an asset is anything of value and worthy of protection.  Information Security is a discipline of protecting information assets from threats through safeguards to achieve the objectives of confidentiality, integrity, and availability or CIA for short. On the other hand, disclosure, alteration, and disruption (DAD) compromise the security objectives.
