I have an on-premises sharepoint team site collection, and it has 25 sub-sites. now i want to migrate this on-premises site collection and its sub-sites to be inside sharepoint online. and i want to follow the new Flat structure, so instead of having sub-sites, i will have 25 modern site collections linked to a hub-site. so i am planning to follow this migration appraoch:-
- migrate our on-premises root site, to be a modern hub site.
- migrate all the 25 sub-sites to be modern team site collections linked to the modern hub-site.
but one of the challenges i will be facing is how i will be managing the site columns and content types for my 25 site collections?. where in the on-premises case, i always create the Site Columns and Content Types on the root site, and re-use them on the sub-sites. but with the flat structure, i can not do the same. and i will need to use the traditional Content type hub site. But my question is:-
If we should invest in Content type hub sites, which can be considered as an old/traditional approach? and is it a future proof appraoch to use CT hub sites with modern sites and flat structure? OR if we want to follow the flat structure then it is better to manage the site columns and content types separately inside each modern site collection, and not to depend on CT hub sites? and seems the flat structure is not supporting content type and site columns re-usability...
