SharePoint is a complex platform. You need to understand the key structural elements of a SharePoint environment to be able to deploy it.
It is vital that SharePoint is configured in the correct way before migrating any data.
Get the deployment wrong and your organisation may never see the true value of the platform. Get it right and you will get an instant return on your investment.
If you are lacking skills in-house leave it to the experts. Use a SharePoint Gold Partner for a well-planned, fast and cost effective deployment.
