I am planning to migrate our On-Premises SharePoint 2013 enterprise farm to office 365 (SharePoint online).
For migrating the sites, I am planning to do the following main tasks:-
Develop and deploy my server side event receiver to work as remote event receivers.
Using third party tool, I am going to migrate the site settings and data.
but the third party tool mentioned that every thing can be migrated from on-premises to office 365, except for the user alerts. where these users' alerts can not be migrated.
so my question is, if there is a way to migrate the users' alerts from on-premises to office 365? or this operation is not supported inside SharePoint ?
