Hi,
I’m using SIgn-in widget 7.18.0 on a SPA application with a Classic Engine tenant; the flag useClassicEngine is true and everything is working fine.
When will we migrate the tenant to OIE, should we immediately set this flag to false or can we keep it as true until the following application update?
Here you can find our OIE upgrade guide with the recommended aspects that you would need to change in order to get your tenant up and going for on OIE: Identity Engine upgrade overview | Okta Developer
After upgrading to the OIE tenant, you would need to remove the useClassicEngine is true snippet.
