Migration from SharePoint 2010 to SharePoint Online can look daunting at the first look. But, the reality is that the actual migration is easy. Although, the hardest nut to crack is the planning part. Prior to initiating the migration process, you need to be doubly sure that you have considered everything, even the minute details of the migration process. That becomes the actual headache.
Before going to the checklist that will eliminate all your migration worries, let us have a quick brief on different migration methods.
This requires no manual intervention, but the downside is that it can only be determined on a ‘scenario’ basis and can’t suit every project. You have Office 365 Migration API, custom coded 3rd party tools etc. to assist the process.
This is the safest and simplest migration to do. But think of the time it takes and the pain we might feel on the manual work of copy pasting content all over. That kind of monotonous job is prone to human error and extremely wearisome too.
So, what is the best take? Yes, you got the answer. We should combine the best of both the worlds. A part of your environment may be the best fit for Automated Migration. Just go with it. And there will be sections which require manual intervention. You decide which is best for your environment and take a call.
The 2010 project solution cannot run directly in 2016. So, you should upgrade your custom farm to 2016. Before taking up the actual migration, it is best to keep the below things on track.
- SharePoint 2010 should be updated with all the latest service packs & patches Microsoft rolled out
- It is advisable to delete all unused features
- Remove Sites, Users and other details not used in SharePoint 2010
