While Telegram remains one of the most mature platforms for bot development, new messengers appear every year and attract users with specific features, better moderation policies, or business-oriented tools. MAX is one such messenger: it has been steadily gaining adoption in the Russian-speaking corporate segment, which is why developers increasingly ask the same question: how do we move our bot from Telegram to MAX without rewriting everything from scratch?\n\nA recent publication on Habr (source) answers this question. The article describes the migration of a production bot from Telegram to MAX, the architectural choices the team made, and the compatibility layer that allowed them to reuse most of the existing logic. This review summarizes the key points of that project and formulates a practical checklist for anyone planning a similar move.\n\n## Why Telegram-to-MAX migration is harder than it looks\n\nAt first glance, moving a bot from one messenger to another looks like replacing a few API calls.
