Adobe Sign → DocuSign Migrator

A Python toolkit for migrating library templates from Adobe Sign (Acrobat Sign) to DocuSign. It downloads templates via the Adobe Sign API, converts them to DocuSign format, and uploads them via the DocuSign API.

What it does

Authenticates with Adobe Sign via OAuth (one-time browser flow, tokens saved to .env)
Downloads all visible library templates — PDF, metadata, and form field definitions
Converts each template to a DocuSign envelopeTemplate JSON, mapping all field types, coordinates, and recipient roles
Uploads the converted template to DocuSign

Prerequisites

Python 3.10+
Node.js 18+ (for the DocuSign upload CLI — uses the esign-direct package)
An Adobe Sign OAuth app (EU2 shard) with scopes: library_read:self library_write:self user_read:self
A DocuSign developer account with an integration key and RSA keypair

Setup

1. Install Python dependencies:

pip install -r requirements.txt

2. Create a .env file in the project root (never commit this):

ADOBE_CLIENT_ID=your-adobe-client-id
ADOBE_CLIENT_SECRET=your-adobe-client-secret
ADOBE_REDIRECT_URI=https://localhost:8080/callback
ADOBE_BASE_URL=https://api.eu2.adobesign.com/api/rest/v6/

DOCUSIGN_ACCOUNT_ID=your-docusign-account-id
DOCUSIGN_INTEGRATION_KEY=your-integration-key
DOCUSIGN_BASE_URL=https://demo.docusign.net/restapi
DOCUSIGN_PRIVATE_KEY_PATH=/path/to/private.key
DOCUSIGN_USER_ID=your-docusign-user-id

3. Authenticate with Adobe Sign (one-time):

python3 src/auth_adobe.py

This opens a browser. After authorizing, paste the redirect URL back into the terminal. Tokens are saved to .env and auto-refreshed on subsequent runs.

Running a migration

Download all templates from Adobe Sign:

python3 src/download_templates.py

Downloads to downloads/<template-name>__<id>/ — one folder per template containing metadata.json, form_fields.json, documents.json, and the PDF.

Convert a downloaded template to DocuSign format:

python3 src/compose_docusign_template.py

Writes DocuSign template JSONs to migration-output/<template-name>/docusign-template.json.

Upload to DocuSign:

node packages/esign-direct/build/cli.js templates create --file migration-output/<name>/docusign-template.json

Or run the full pipeline end-to-end for a specific template:

python3 src/migrate_paul_template.py

(Edit the TEMPLATE_NAME constant at the top of the script to target a different template. If multiple templates share the same name, the most recently modified one is used.)

Field type mapping

See field-mapping.md for the full Adobe Sign → DocuSign tab type table, including edge cases and known gaps.

Known API quirks and bugs

See tests/PLATFORM-QUIRKS.md for documented platform bugs, unexpected API behaviors, and the fixes applied.
