I have a CM3.1.2 main core site with 20+ LSP sites all running CM3.x with S8300B servers. Now all the orders for new sites are coming with S8300C servers and CM4.x software due to the end of life with the S8300B. At this stage the client does not want to do any software or harware upgrades to the existing enviroment and I would like to know if any additional LSP sites can be added to the core site as S8300C LSP running CM4.x or will the LSP and core site not filesync correclty?
