Before you begin: planning and prerequisites

  • Assess your data size and structure. Run a scan on your Dropbox/Google Drive to measure total size, number of files, and large folders. This helps choose storage, bandwidth, and migration approach.
  • Decide on hosting. Options: self-host on a VPS, dedicated server, or use Seafile’s cloud hosting or a third-party managed provider. For large teams or sensitive data, prefer a VPS or dedicated server with RAID and regular backups.
  • Choose Seafile edition. Community Edition (CE) is free and covers core syncing and file libraries. Professional/Enterprise editions add features like advanced permission controls, built-in LDAP/AD integration, full-text search, and audit logs.
  • Inventory shared items and permissions. Document shared folders, external links, and collaborators in Dropbox/Drive; you’ll need to recreate equivalent shares in Seafile.
  • Plan user accounts and authentication. Map Dropbox/Google accounts to Seafile accounts. Decide whether to use local accounts, LDAP/AD, or SSO (SAML/OAuth2).
  • Backup everything. Export and keep a copy of all data and metadata before migrating.

Step 1 — Export data from Dropbox or Google Drive

Dropbox:

  1. Use the Dropbox desktop client to sync all files locally, or use the web interface to select and download folders. For large accounts, use the Dropbox “Export” feature or the Dropbox API (with a script) to retrieve files programmatically.
  2. If you need file metadata (sharing info, comments), use the Dropbox API to export metadata JSON for later reference.

Google Drive:

  1. Use Google Drive for desktop to sync files to a local folder, or use Google Takeout to export Drive contents. Google Takeout is helpful for large exports and preserves directory structure.
  2. To preserve sharing settings and permissions, use Google Drive API to list file permissions; export these records for recreation in Seafile.

Notes:

  • Exports may produce ZIP archives; unzip to a working migration directory that preserves folder structure.
  • Preserve file timestamps and use tools that maintain modification times (rsync with -a or similar).

Step 2 — Prepare Seafile server and environment

  1. Install Seafile:
    • For small teams, Seafile Community Edition on Ubuntu/Debian is common. Follow Seafile’s official install docs for your OS.
    • For production or larger teams, use Seafile Professional or Enterprise, which provide extra features and support.
  2. Provision storage:
    • Ensure your server has enough disk space for current data + growth. Consider SSD for metadata/db and HDD for bulk storage.
    • Configure backups and snapshots (daily incremental + weekly full).
  3. Setup database and services:
    • Seafile uses MySQL/MariaDB or PostgreSQL. Create the appropriate DB and user.
    • Configure Redis for caching if recommended by Seafile version.
  4. Configure HTTPS and domain:
    • Obtain TLS cert (Let’s Encrypt) and ensure web access is secure.
  5. Create users and libraries:
    • Pre-create user accounts according to your mapping plan, or configure LDAP/SSO so users can sign up with existing credentials.
    • Decide library structure: Seafile uses libraries (top-level containers) which can map to major folders from Dropbox/Drive.

Step 3 — Import files into Seafile

Option A — Manual upload via web UI (small datasets)

  • Create libraries in Seafile web UI corresponding to top-level folders from Dropbox/Drive.
  • Upload files/folders through the browser. This is simple but slow and impractical for large datasets.

Option B — Seafile client sync (recommended for many users)

  1. Install Seafile desktop client on a migration machine.
  2. For each library, create a local folder and copy the exported Dropbox/Drive contents into that local folder.
  3. Link the local folder to the Seafile client and let it sync to the server. This preserves file timestamps and is robust.

Option C — Server-side direct import (fastest for large datasets)

  • Use Seafile’s seaf-fsck or seahub-import tools (depending on edition and version) to import files directly into Seafile’s file store. This method is more advanced and may require:
    • Preparing import directories to match Seafile’s storage layout.
    • Generating library objects via APIs or scripts.
  • For very large migrations, consider writing a script that uses Seafile’s REST API to create libraries and upload files in batches. Benefits: resumable, programmatic control, and metadata mapping.

Example: Python script using Seafile API (high-level steps)

  1. Authenticate to Seafile REST API and create a library.
  2. Recursively walk the local export folder, creating directories via API and uploading files in chunks.
  3. Track progress and retry failed uploads.
  • Recreate team shares and group permissions in Seafile according to your inventory.
  • For public share links:
    • Dropbox/Drive links will not redirect. Reissue public links from Seafile and communicate them to collaborators.
    • If you control DNS and want to preserve old links, set up redirect pages or use shortlinks that map old link identifiers to new Seafile links.
  • For folder-level permissions:
    • Map Dropbox/Drive collaborators to Seafile users or groups; assign Read/Read-Write as needed.
  • For comments and file histories:
    • Notes and comments typically cannot be migrated automatically; export them for archival purposes and inform users.

Step 5 — Preserve version history and metadata (if needed)

  • Version history is often important. Options:
    • Dropbox and Google Drive maintain version histories; export previous versions via API and upload them as separate files (e.g., in a .versions folder) if Seafile import cannot set historical timestamps and version entries.
    • Some migration scripts can upload older versions by setting timestamps and using Seafile’s versioning API (if available). Check your Seafile edition docs.
  • Preserve timestamps using rsync -a or tools that set mtime/atime during upload or after files are in place (via touch -d).
  • Store original sharing metadata and comments as an archive file within each top-level library for reference.

Step 6 — Client rollout and user cutover

  1. Communicate timeline:
    • Tell users about migration windows, expected downtime, and any actions they must take (e.g., stop syncing with Dropbox/Drive during cutover).
  2. Install/configure Seafile clients:
    • Provide installers and documentation for desktop and mobile clients.
    • If using SSO/LDAP, ensure users can authenticate before broad rollout.
  3. Perform cutover:
    • Ask users to pause or quit Dropbox/Drive sync clients to prevent conflicting changes.
    • Sync final delta changes: copy any new/changed files from Dropbox/Drive to Seafile migration folders, or use a differential sync tool (rsync –update) to catch changes since initial export.
  4. Verify:
    • Spot-check file integrity, permissions, and sharing links.
    • Ask a subset of users to test typical workflows (upload, share, edit).

Step 7 — Post-migration tasks

  • Decommission or repurpose Dropbox/Drive after a grace period. Keep read-only access for a while in case users need to retrieve missed files.
  • Train users: run short sessions or provide quick-start docs for Seafile features (sync clients, web editing, restore versions).
  • Monitor server performance and storage growth; tune caching, database settings, and backup cadence.
  • Implement regular audits and retention policies.

Common migration pitfalls and how to avoid them

  • Not accounting for shared links and permissions — inventory and reapply programmatically when possible.
  • Ignoring version history — decide whether to archive versions or import them.
  • Underestimating storage needs — plan with buffer for growth and temporary migration copies.
  • Poor communication — users continuing to use old services during cutover cause conflicts; enforce a read-only period.
  • Skipping backups — always keep a full backup of the original source until migration is validated.

Sample checklist (short)

  • [ ] Inventory files, size, shares, and permissions
  • [ ] Choose hosting and Seafile edition
  • [ ] Backup original data (Dropbox/Drive export)
  • [ ] Install and configure Seafile server (DB, HTTPS, users)
  • [ ] Import files via client sync or API scripts
  • [ ] Recreate shares and public links
  • [ ] Migrate version history or archive it
  • [ ] Communicate cutover and pause old sync clients
  • [ ] Verify integrity and performance
  • [ ] Decommission old service after grace period

If you want, I can:

  • Provide a sample Python script to upload files to Seafile via its REST API.
  • Help design a migration schedule for a team of a specific size.
