My two cents here:
(1) No replacement Today for BCS in SPO. BCS is in SPO, but Microsoft has not invested in the service for years, so I would carefully think on using it in an alternative you could expose the data to be integrated in a API you can integrate with a SPFx Custom Dev
(2) Event Reveivers are not supported in SPO, the alternatives you have are: Webhooks, Power Automate Flows or Azure Functions
Thank you ! but while migrating data will lose without BCS right ?
