💡 High-Priority Features Under Investigation

☁️ Google Workspace & Microsoft 365 to Nextcloud Migration

• Concept: Direct, end-to-end migration pipeline from proprietary big-tech ecosystems (Google Workspace and Microsoft 365) to private, sovereign Nextcloud instances.
• Scope & Capabilities:
  • Email & Mailbox Transfer: Seamless modern OAuth2 / IMAP transfer into Nextcloud's underlying mail backend (Dovecot, Stalwart, Mailcow, Postfix) with automatic folder structure alignment.
  • Nextcloud Provisioning & Auto-Configuration: Auto-detection and direct connection via Nextcloud Provisioning API (OCS) and Nextcloud Mail app endpoints.
  • Groupware Expansion (Contacts & Calendars): Automated migration of address books (Google Contacts / Outlook People) to Nextcloud Contacts via CardDAV, and events (Google Calendar / Outlook Calendar) to Nextcloud Calendar via CalDAV.
  • Drive to Nextcloud Files (WebDAV): Optional data and document migration from Google Drive / OneDrive into user Nextcloud storage directories.
• Benefit: Empowers organizations, enterprises, and privacy-conscious users with a 1-click sovereign exit route from Google Workspace and Microsoft 365 to private Nextcloud infrastructure with zero vendor lock-in.

🔄 Smart Folder Normalization & Mapping

• Concept: Automatic translation and mapping between different server folder naming conventions.
• Benefit: Prevents duplicate system folders on the destination (e.g., mapping Outlook's Sent Items directly into cPanel's Sent, or mapping localized folder names like Gelöschte Elemente to Trash).

📊 Exportable HTML Migration Audit Reports

• Concept: A one-click generation of comprehensive, styled HTML summary reports alongside the existing CSV and TXT log exports.
• Benefit: Generates a professional proof-of-work report (accounts, folders, messages copied vs. skipped, speed, and any error logs) ideal for IT consultancies and managed service providers delivering migration sign-offs to clients.

🔁 1-Click "Retry Failed Only"

• Concept: In a batch migration with dozens of mailboxes, if any accounts fail (e.g. due to bad credentials or transient server dropouts), a dedicated button will instantly filter and re-run only the failed accounts.
• Benefit: Saves time by not needing to re-evaluate the successful mailboxes in the batch.

⚡ Bandwidth Throttling & Rate Limiting

• Concept: An optional slider to limit maximum download/upload speed (e.g. limit to 10 MB/s) or pause briefly between accounts.
• Benefit: Prevents aggressive ISP bandwidth saturation or mail server rate-limiting bans on shared connections.

📅 Date Range Filtering

• Concept: Give users the option to migrate only emails received after a certain date (e.g. "last 6 months", "last 1 year" or a custom start and end date).
• Benefit: Very helpful when migrating users with strict mailbox size limits or who only need recent correspondence transferred to a new cloud mailbox.

🗑️ Selective Folder Exclusion (Skip Trash & Spam)

• Concept: Quick-toggle options to skip Trash, Deleted Items, Junk, and Spam folders during migration, plus custom wildcard exclusion rules (e.g. Archive/2010*).
• Benefit: Drastically reduces transfer time and bandwidth by skipping unwanted emails.

🐧 Cross-Platform Linux & Docker CLI

• Concept: A lightweight, standalone cross-platform console build (linux-x64, linux-arm64) and an official Docker container image (docker run mundofy/mailmigrator ...).
• Heritage & Motivation: The classic imapcopy was our core inspiration and a trusted tool for Linux sysadmins for over a decade. Bringing modern TLS 1.3 encryption, modern 64-bit architecture, POP3 support, and containerized deployment back to Linux will give sysadmins a high-speed modern successor.
• Benefit: Enables automated, headless migrations on Linux VPS servers, Kubernetes clusters, and container pipelines with zero dependencies.
