Migrating From vsftpd to Maftoox FTP Server — Step-by-Step Checklist

Preparation

  1. Inventory current vsftpd setup
    • OS, vsftpd version, config file locations (/etc/vsftpd/vsftpd.conf), enabled features (virtual users, TLS, passive ports, chroot, rate limits), users, directories, permissions, cron jobs, firewall/NAT rules, SELinux/AppArmor policies, monitoring/backup integrations.
  2. Gather Maftoox requirements
    • Target OS, package/repo or build method, required ports, TLS cert locations, user/auth methods supported (system users, PAM, virtual users), feature parity with your current setup.
  3. Plan downtime and rollback
    • Maintenance window, DNS/endpoint cutover plan, backup of configs and data, test server/address, rollback steps (re-enable vsftpd, restore configs).

Test environment

  1. Provision test server
    • Match production OS and network. Open passive and control ports in firewall.
  2. Install Maftoox on test host
    • Follow Maftoox install method (package, binary, or build). Verify service starts.
  3. Replicate vsftpd configuration
    • Translate vsftpd settings to Maftoox equivalents: anonymous/local_enable, chroot_localuser, TLS settings, passive port range, virtual-user mappings, per-user configs, logging paths, bandwidth limits, umask.
    • Create sample Maftoox config file and document differences.

Authentication & Users

  1. Migrate user accounts
    • If using system users: create identical accounts and home directories, set ownership/permissions.
    • If using virtual users/PAM: export virtual user database and import or configure equivalent Maftoox virtual-user backend (e.g., DB, file, LDAP).
  2. Passwords and keys
    • If migrating passwords: use secure export/import or require password reset. If using SSH keys or other tokens, configure Maftoox to accept them.

Data and Permissions

  1. Sync data
    • Rsync or copy FTP directories to Maftoox server, preserving ownership, permissions, and timestamps: 
      Code
      rsync -aHAX –numeric-ids /srv/ftp/ user@maftoox:/srv/ftp/
  2. Verify quotas and disk limits
    • Recreate any quota rules or storage limits on the new host.

TLS/Certificates

  1. Install TLS certificates
    • Copy or reissue cert/key and configure Maftoox TLS settings (cipher suites, TLS versions) to match or improve security. Test with an FTP client supporting TLS.

Network & Firewall

  1. Open and test ports
    • Ensure control (21) and passive range are allowed; update NAT if behind router. Test active and passive transfers.
  2. Adjust firewall/NAT and SELinux
    • Update rules for Maftoox service, apply SELinux/AppArmor policies as needed.

Functional testing

  1. Basic connectivity tests
    • Login as admin, local user, virtual user, anonymous (if used).
  2. File operations
    • Upload, download, rename, delete, list directories; test large-file transfers and binary/ascii modes.
  3. TLS enforcement
    • Test forced TLS logins and encrypted transfers.
  4. Edge cases
    • Concurrent connections, resume transfers, passive/active mode, permissions errors, symbolic links.

Performance & Monitoring

  1. Performance tuning
    • Adjust connection limits, timeout values, thread/process model, passive port range, buffers, and any Maftoox-specific performance parameters.
  2. Logging & monitoring
    • Configure logs, rotate policies, and integrate with existing monitoring/alerting (Prometheus, syslog, Nagios, etc.).

Security hardening

  1. Harden Maftoox
    • Disable anonymous if unused, enable chroot or jailed users, restrict writable directories, apply fail2ban or connection throttling, ensure up-to-date TLS ciphers.
  2. Review permissions
    • Minimize privileges for Maftoox process user and verify filesystem ownership.

Cutover

  1. Final sync
    • Rsync changes since test sync (use –delete if appropriate) during maintenance window.
  2. Switch service
    • Stop vsftpd, start Maftoox on production IP/port. Update DNS if using a different host.
  3. Smoke tests
    • Repeat functional tests, confirm monitoring alerts, and verify backups run.

Post-migration

  1. Monitor and validate
    • Monitor logs, performance, and user reports for 48–72 hours.
  2. Decommission vsftpd
    • Once stable, archive configs and data, remove or disable vsftpd packages, and update documentation.

If you want, I can:

  • generate a concrete Maftoox config translated from your vsftpd.conf (paste it here), or
  • produce a runnable rsync + systemd cutover script for your environment.
