In Jainism, there isn’t a standard or canonical practice of “converting” idols from Digambara to Śvetāmbara or vice versa. The two Śrāvak traditions have different iconographic rules and monastic codes, but both revere the Tirthankaras (the 24 Jinas) and aim to honor the same spiritual goal. Here’s the gist:

• Digambara iconography: Tirthankaras are depicted nude (symbolizing renunciation) and the tradition emphasizes their perfect, unrevealed form tied to Digambara rituals and monastic code.
• Śvetāmbara iconography: Tirthankaras are depicted clothed, with different stylistic conventions and temple rituals that align with Śvetāmbara practice.

If a temple were to change the installed idol from one tradition to the other, it would not be a simple “conversion.” It would amount to a reinstallation/consecration process under the temple’s governing authority, following the appropriate rituals of the new tradition and with guidance from their Jain teachers. The spiritual focus remains on the Jina and his teachings, not on sectarian labels.

If you want a precise, tradition-specific explanation (Digambaras vs. Śvetāmbaras) or guidance on the proper procedures and prayers associated with such a change, I can share a concise, source-backed summary in the Jain framework.
