The Manual Migration Check- Technical Case Study

Before opting for a professional solution, IT teams and individuals attempt “manual IMAP-supported drag and drop.” We tracked the routine transfer of 4,500 Pegasus emails (PMM) into MS Outlook to analyze technical results.

Scenario:
A mid-sized legal organisation was retiring its old "Pegasus" mail server and transferring its archive files to a more contemporary PST format. Now, here’s what the analysis depicts:

Manual Migration SysInfo Pegasus Mail Converter
Requires high technical effort, such as setting up a local server and connection. No technical efforts required, instantly reads PMM, CNM, PNM, PMI, and other files from the disk.
Loss of headers and read/unread flags Attachments are often detached or transferred incompletely Preserves 100% data integrity All attachments are securely saved or embedded with output
Requires consistent monitoring for timeouts Automates rapid batch processing with real-time live logs

Outcome:

Manual attempt by the organization resulted in approximately 11-14% data fragmentation. Especially found in the non-English character coding and Pegasus files with complex data. On the other hand, SysInfo completed the same data conversion in minimal time with zero integrity errors or downtime. Thus, making it feasible for enterprise environments.

Frequently Asked Questions

Listed Below are Generally Asked Questions and their Respective Solutions

Q1.  What professionals, teams, and businesses understand by Pegasus Converter?

Ans: The SysInfo Pegasus Converter is a standalone Windows desktop tool to read and convert Pegasus PMM, CNM, PNM, PML, PMF, PMC, and PMI files in 12 universally supported formats. This means users can convert Pegasus mail to MBOX, PST, PDF, EML, EMLX, CSV, MSG, HTML, RTF, MBX, MD, and DOCX. Entire offline processing. No server and application required. Complete data fidelity throughout the conversion.

Ans: No. The Pegasus Mail Converter reads mailbox files directly from the disk without any Pegasus Mail or another client installation. Reads data stored in an independent Pegasus proprietary format at the file system level. Convert legacy Pegasus emails and content archives of 10 to 15 years without risks and hassle.

Ans: Yes You can filter by: date range, sender, subject keyword, size, and read/unread status to choose emails selectively. Multiple filters can be combined together. For example, you may choose to only export a single unread email from a particular sender that was received after May 2020; in that circumstance, all active filters would be applied simultaneously to the emails being converted.

Ans: Yes. Technically, there is no limit on how many email messages can be contained within a Pegasus folder. In fact, users report successfully converting mailboxes with more than 30,000 email messages at one time in Pegasus Exporter.

Ans: Of course, yes The folder structure, email headers, timestamps, and attachments are kept exactly how they were in the original mailbox. No need for any additional processing or changing of output files. Attachments are exported separately from the original email as files in the exported output folder structure and kept in their original format.

Ans: During the free trial period, you can export upto 50 messages per folder for each of the 12 output formats. All other filters and features are all fully functional during the trial period, so you can evaluate the quality of the exported files before purchasing the SysInfo PST Mail Converter Tool.

Ans: Size filters are available for four different categories of emails: all sizes, small (< 100 KB), medium (100 KB - 1 MB), and large (> 1 MB). Size filters can be used in conjunction with the read/unread status filter and are useful for quickly recovering recent unrevised messages of known sizes. For example, recovering only the largest emails that may have attachments.

Ans: Yes, you may use the custom naming feature to name the folders before conversion begins. Also, use the date-based naming feature to automatically name the files converted based on the date of the email for sorting emails easily when working with large backlogs of emails.

Ans: Pegasus Mail Converter Tool performs the conversion offline and accesses the uploaded files in read-only mode. Nothing is uploaded to the server, and no files are modified. This means that your data is completely safe on your computer without any risks.

Ans: No, for users For users with few files, the process completes in minutes. Even for those with large and bulky data volumes, the conversion takes place in no time due to the fast processing capability of the SysInfo Pegasus Converter Tool. No requirement for technicality as it completes conversion with a simple 3-step process: Upload and preview files, select output and apply filters, convert and save data.

Ans: Yes. You can avail SysInfo One-Time Service and have a no software installation Pegasus conversion. Through this remote migration service, our technical experts handle the entire process, ensuring a simplified and enhanced user experience without cluttering your system with extra applications.

Our Client Testimonials

Find out what migration teams and end-user reviews say about SysInfo

"The outdated server on which Pegasus Mail was running recently closed down. This legacy server has nearly 40,000 emails across many different users and accounts. The bulk processing option of the SysInfo Pegasus Mail Converter allowed us to convert multiple Pegasus emails at once and kept every folder organized as in the original mailbox. This saved several days' worth of manual workload."

"The filters based on date range/keyword are highly usable. I was able to export project-related emails (2 years' worth) from a particular sender, without exporting any irrelevant emails, using this professional PST Exporter Tool. The output was clean and named accordingly and instantly ready for client delivery."

Sophie Caden,
Migration Specialist,

"What I liked most about this SysInfo Pegasus Converter is that it works without needing to have Pegasus Mail installed. We have around 500+ Pegasus emails of 50 MB each, and the converter successfully read all of the files from disk without any problems. It converted them all with 100% accuracy, and this is the way the migration tool should work."
