Frequently Asked Questions
Everything you need to know before migrating from Stellar® Converter
Why is Prism Migration a better alternative to Stellar Converter for Outlook?
Prism Migration provides a flat $49 lifetime license (saving you $99 every single year), runs natively on Apple Silicon macOS as well as Windows 11, and operates 100% standalone without requiring Microsoft Outlook or MAPI drivers.
Does Prism Migration require Microsoft Outlook to be installed like Stellar?
No. Unlike Stellar Converter which frequently requires an active Outlook installation or MAPI configuration to export data, Prism Migration uses a proprietary 64-bit byte-stream parser that reads raw PST structures independently.
How does Prism Migration handle massive 50GB to 100GB+ PST files?
Prism uses a memory-safe iterator pattern with SQLite checkpointing. It processes messages sequentially without loading the entire multi-gigabyte file into RAM, eliminating out-of-memory crashes on large archives.
Can I try Prism Migration before buying?
Yes. You can download the free evaluation trial directly from the product page. It lets you scan, preview, and convert sample items from your mailbox archives with zero credit card required.
