What are the different factors for getting started with Office 365?

Assessment of Existing SharePoint Environment

Before deciding on a migration strategy it is vital that you perform an analysis of your current environment then carefully plan the different aspects of SharePoint, Exchange and Lync.

SharePoint Content Migration

If you plan to migrate SharePoint content from an on-premises or hosted service to SharePoint Online, your organization will either use a manual approach or to use a third-party SharePoint migration tool.

One way to manually move content to SharePoint Online is by connecting the SharePoint Library to SharePoint Workspace. You can then upload content to SharePoint Workspace and it will automatically synchronize these files to SharePoint Online. Another manual approach is to use the capability of SharePoint to upload multiple files. This will allow you to upload batches of files at once.

Note:
If you use the manual migration methods described above, the uploaded files will appear as being created by the user who uploaded them. Also the timestamp of the file will be the upload time and not the original creation time.

Before choosing the migration tool to migrate your SharePoint content, be sure to verify that the tool meets your migration requirements and that it supports all of the SharePoint artifacts you want to migrate. Refer to the third-party tool’s documentation and evaluate what preparation steps your organization will need to implement.
