Migrate from C5 to C6, what synchronisation I should take care of ?

Migrate from C5 to C6, what synchronisation I should take care of ?

Hi,

We have multiple applications in C5. Goal to is migrate to C6, but these applications have connections with other Zoho apps (CRM and Books), and also external websites with incoming and outgoing webhooks (REST API).

When migrating to C6, how these synchronisation and REST API calls are managed ? Will they got broken ? Is there a downtime ? Should I recreate all connexions ?

Anybody has feedback with this ? I try to prevent any problem in running apps.

Regards
