morphir ir migrate

  • Usage: morphir ir migrate [FLAGS] <INPUT>

Migrate IR between versions

Converts concrete Morphir IR V3 and V4 between native JSON and YAML storage, single files, and V4 document trees. V3-to-V4 output defaults to YAML.

Examples:

# Migrate V3 JSON to the default V4 YAML profile
morphir ir migrate ./morphir-ir.json -o ./morphir-ir-v4.yaml

# Convert V4 YAML to JSON without changing the IR version
morphir ir migrate ./morphir-ir-v4.yaml -o ./morphir-ir-v4.json

# Migrate from URL
morphir ir migrate https://lcr-interactive.finos.org/server/morphir-ir.json -o ./lcr-v4.json

# Stream YAML IR to stdout (no -o)
morphir ir migrate ./morphir-ir.json

# Write the V4 document-tree layout
morphir ir migrate ./morphir-ir.json -o ./morphir-ir-v4/ --output-layout vfs

See the IR Migration Guide for detailed real-world examples including the US Federal Reserve FR 2052a regulation model.
