We have SharePoint online as well as on premises in our organisation. Recently we have decided to use only online. I know there are third party tools such as share-gate or metalogix which allows as to do this. But our contents on the on prem is pretty small and we do not want to move all the details to the online plat form. Plus there is the cost factor as well.
I know that we can copy the contents manualy by then there will be a problem of metadata,created by, modified by and date fields. What is the alternative ? if you could provide some documentation or a step by step guide to do this that will be great.
