Before you upgrade to n8n 3.0

2 things in this workflow are removed in n8n 3.0. Fix them before you upgrade:

HTTP Request Tool (legacy) in update_lead_dispostiotn, update_businesses_type, update_weekly_inquery…: replace with HTTP Request node connected to the AI Agent's Tool input.
AI Agent v1 (old agent modes) in AI Agent (v1.6): replace with Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent.

Rather not rewrite it? Many of these flows can be rebuilt in Make (free plan).

Removed in 3.0	Replace with
HTTP Request Tool (legacy) update_lead_dispostiotn, update_businesses_type, update_weekly_inquery, update_current_response_times, update_team_sizes, update_operation_bottleneck, update_monthly_revenues, get_availability, reschedule_appointment, schedule_appointment, update_previous_experience_with_aIso	HTTP Request node connected to the AI Agent's Tool input
AI Agent v1 (old agent modes) AI Agent (v1.6)	Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent.
