Heads up: the Foundation Build-on-Canton KB snapshot of versions is behind the live release stream (it last said Canton SDK 3.5.18 / Splice 0.8.3). The numbers shown above are derived from github_releases and the validator-announce mailing list and are current. The deprecation table below remains valid. Those CLI / package replacements don't change with point releases.

General migration path

If you're moving an existing project off the legacy Daml-assistant stack, the broad strokes look like this. Match the specific items above for command-by-command replacements:

Progress0 of 5 · 0%

Install DPM.One-liner above. daml-assistant stays installable for Canton 3.3 / Splice 0.4.x projects but the new tooling is dpm.DPM install command
Swap CLI commands.daml start/build/test/new become dpm sandbox / dpm build / dpm test / dpm new.CLI commands in the lookup
Swap JS packages.@daml/ledger → @c7/ledger, @daml/react → @c7/react (community-maintained drop-ins).npm packages in the lookup
Replace Navigator / Daml Triggers / DAR-upload CLIwith calls to the JSON Ledger API (port 7575) or gRPC Ledger API. The deprecated commands above are thin wrappers. Your backend can call the same endpoints directly.Canton docs (opens in a new tab)
Token-standard workflows.If you used splice-wallet-payments subscriptions, move to the Token Standard (CIP-0056) DVP workflows.CIP-0056

For AI agents

Same data through three other surfaces:

migrate_lookup: MCP tool. Input: deprecated command or package name. Output: replacement, note, since-version. /for-ai for the contract.
list_deprecations: MCP tool. Output: all 24 pairs with category filters.
GET /api/v1/migrate Returns a JSON list of every deprecation entry. Add ?q=daml+start for best-match lookup, or ?category=cli to filter.
get_current_versions: MCP tool. Returns the freshest Canton SDK, Splice, DPM, Daml versions plus per-network Splice deployment status, derived live from github_releases and the validator-announce mailing list.
GET /api/v1/versions JSON shape: {canton, splice, daml, dpm, foundationKb}. Use this instead of /api/v1/migrate when you only need current versions.

What this is NOT

Not an exhaustive migration guide. It's a lookup table. Project-specific migration notes live in the upstream docs at docs.canton.network.
Not a code rewriter. No codemod, no automatic patching. CCPEDIA tells you what to change; you change it.
Not authoritative. If the entry here conflicts with current upstream docs, trust the upstream, and please tell me so I can sync the table.
