Everyone talks about licensing and training. The real gut punch comes after you've signed the dotted line.
Think about rebuilding all those reports and dashboards your team actually uses. Not the shiny ones for leadership, the grunt-work ones that make the quarter happen. Then there's redoing all your data connections and ETL jobs. Your "one-click migration" vendor promised? Pure fiction. And don't get me started on the hidden tax of re-training your power users, who will suddenly forget how to filter a table.
Oh, and your historical data? Either you pay a fortune to keep the old tool running in parallel for a year, or you lose all comparative trend analysis. There's no magic button. Just months of sunk cost and grumpy sales ops managers.
