SharePoint product has had a very drastic transition over the past few years. Many features are deprecated and many solution practices which we used to follow are no more supported. So this blog will give you details of the things to watch out for or to be remediated before you move into cloud.
No farm solutions
No Sandbox code
No public sites (Anonymous sites)
If you are having an extranet built on SharePoint with anonymous public sites, then those site cannot be migrated to Office365 because Microsoft has officially stopped Public sites feature in Office365. This leaves you with options to move those sites to Office365 partner website (See Use a public website with Office365) or you can go for a hybrid model with all public sites inside your on-premise farm.
Assess your farm before migration
You can use below tools to assess your farm for farm solutions and other configurations which can cause you problems while migrating to office 365.
- SPCAF Code Migration tool paid tool but gives you a detailed report and guidance on how to transform your current solutions into cloud compatible solution.
- SharePoint Migration Assessment tool (SMAT): This is a free tool made available by Microsoft. Run this tool in your farm and it will scan your farm and give you insights on the solutions which will impact your cloud migration.
