      python3 <(curl -s -S -L https://git.io/gwmme-create-service-account)
    • Then, download the JSON file containing the service account’s client ID.

  • Then, place PST files in the respective user folders.

Step 5. Create CSV Files:

  • Control CSV: Source user, Target user (for PST file migrations: PST folder name, Target user)
  • Mapping CSV (required if user addresses differ): Source user, Target user (if addresses are the same, omit “Target user”)
  • Calendar events and resources: if addresses are different use: Source resource address, Target resource address

Downsides Users Face While Using Manual Methods

While GWSMO and GWMME are the native tools provided by Google Workspace and are useful, they prove to be incompetent for large enterprises that deal with thousands of data points in bulk.

  • Traditional methods like the above-mentioned typically take a lot of users’ time and energy while handling multiple PST files, since the process requires repetitive steps.
  • Consists of a high risk of users performing errors, which could result in incomplete information, transfers, and integrity issues.
  • Not suitable for beginners and non-technical users due to the complex knowledge of steps and procedures.
  • Does not guarantee for seamless transfer of data, which could lead to data loss of calendars, contacts, and disorganization of information.
  • Manual techniques tend to have file limitations, which restrict large files or mailboxes from transferring as a whole and splitting them into numerous parts.

Frequently Asked Questions

Q1. Alongside emails, what other data will I be importing when I migrate PST files to a G Suite environment?
Ans. Admins can potentially have PST files comprising tasks, notes, and journal entries. However, it should be noted that direct support for these data types may not be there in Google Workspace. Other than that, the tool prescribed in the above sections can deposit contacts, calendars, and documents associated with a particular PST file in G Suite.

Q2. How secure is a PST to G Suite Migration?
Ans. Security is a paramount concern for admins responsible for bringing PST files into G Suite. GWMME with service accounts enhances security. Moreover, the tool uses a secure admin-made application ID and .p12 verification system that only allows authorized personnel to conduct the import.

Q3. What are the cost implications of each method?
Ans. GWMME may require technical expertise (internal or external cost). Another hidden cost factor is extended downtime. The longer a business has to wait to get back to its usual functioning the more money it loses. Often this loss in potential income is way more than any investment made in Software licensing fees of professional solutions.
