Does the release of SharePoint 2013 have you thinking migration? Some customers will move their legacy SharePoint content, Windows file shares, Exchange public folders and Google Drive docs directly to the new version—whether on-premises or Office 365. Others will migrate to SharePoint 2010, and stay one version away from current.
In any scenario, SharePoint migrations are long, complex, risky and expensive projects. It’s critical that you plan effectively, and utilize the proper tools to ensure success.
