Most enterprise platforms, we've got you covered. We can migrate your data to another on-premise system, Exchange 2010 to Exchange 2016, and to the cloud. Our ability to create and manage co-existent environments provides peace of mind during customer transition periods. This reassures our customers while their new processes are tested and users are trained.

Our long experience has given us great insight to the technology pitfalls associated with merging email systems. We can perform most with little to no interruption for end users.

Upgrading to unsupported versions?

Many customers will let maintenance "slide" on their archive systems and at some point need support. They find out that the version they are running is no longer supported and they cannot perform a stepped upgrade. We have a solution to move most archive systems several versions ahead without a stepped" upgrade.

Decommissioning your Archive System?

Once your organization has decided that their archive system no longer meets its business needs, or you would like to move your archived data to new platform, you will have to "decommission" the archive system. This process can put your data at risk and greatly impact end-users if not performed correctly. Cornerstone has lots of experience with decommissioning archive systems if needed. Let us guide you to a safe outcome.

How's your Archive System running?

Cornerstone has had so many requests over the years to "fix" archive systems that are not working and or performing badly. This led us to developed an "Archive Health Check" process. We have developed custom tools and reports for this process. During a health check we can uncover many areas that may be causing poor performance. Once we have identified the issue we will deliver a report with actionable tasks that your team or ours can then perform to resolve performance issues.

Active Directory

Domain Migrations and Consolidations

CST has vast experience with domain migrations and consolidations. We can migrate one domain to another domain, multiple domains into one domain such as during a merger or acquisition. Cornerstone technologies has migrated tens of thousands of Workstations, Servers, Mailboxes and user accounts. We typically can perform migrations with little to no interruption to end users or critical systems. Our team has developed very specialized skills and proprietary tools to do just this kind of work.

  • AD 2003

  • AD2012

  • Multiple Domains

  • AD 2012

  • AD 2016

  • Office365 / AZURE

We have migrated (consolidated) as many as 15 separate Microsoft domains into one Active Directory domain. With little impact on the end users of the system. Our experience with domain migrations has given us good insight into what you need to look out for in the planning, testing and production migration phases of your domain consolidation. We understand the need for systems to coexist uninterrupted during a migration so that the businesses day to day activities are not impacted.

PST File Migrations... PST Headaches Solved

CST has been performing PST migrations from the beginning. We employ several technologies to accomplish this depending on your needs. We can search workstations, servers and network shares. When we (our tools) locate a PST an algorithm is run that determines who the PST belongs to. Then we can move or migrate that PST file into may locations based on you specific needs, such as Office 365 mailbox or archive, 3rd party archive platform, Google or many other cloud platforms. We can perform many functions against the PST where it rests such as move, copy, delete, hide or compress. And as always we can provide complete "chain of custody" reporting to fulfill your legal records requirements.

If you would like more information on how and what we can do to resolve your PST headaches please contact us today.

PST's and Legal Discovery

TransVault Insight one of the leading tools we use for PST migrations has a unique ability that greatly aids in Legal Discovery. It has the ability to locate and search the contents of PST files where they rest whether its on a customers workstation or network share. Using policy based rules we can locate PST files that contain data matching  the criteria of a legal search. This can speed up the process of locating PST files and also greatly reduce the number of PST files that are selected for a final search in your e-Discovery tool or by your legal team. Thereby reducing your litigation coast by a large amount. In some cases millions of dollars saved.
