CLOUD STORAGE MIGRATION

Break free from expensive cloud storage

Overview

Is your data locked into a cloud archive? Or is it stuck on-premises in an outdated archive platform?

We speak with many enterprises whose archive is becoming expensive, difficult to maintain, or that no longer meets their needs.

We can deliver a full-service migration from start to finish. Or, if you’re working with a tight budget, we can support and skill up your in-house IT team to successfully carry out the migration themselves.

BENEFITS

The benefits of our storage migration service

Reduce your storage costs

Cloud storage vendors can sometimes increase their prices or quietly change the terms of your data hosting agreement – leading to unexpected and often significant cost hikes.

Alternatively, on-premises storage can become increasingly expensive and complex to maintain, especially when the rest of your infrastructure has already moved to the cloud.

By migrating all or selected data, you can significantly reduce storage costs – without compromising the critical information your business depends on or needs to retain for compliance.

Get advanced control

Our migrations offer sophisticated control and can cope with virtually any anomaly.

  • Exclude what you don’t need, e.g., items > 7 years
  • Merge archives belonging to the same person (common after a relocation or name change)
  • Identify leavers, orphaned files, etc.

Secure, Compliant Archive Migration

Our team, solutions and processes, will ensure a reliable and compliant migration with services that include:

  • Chain of custody reports account for each message
  • Automatic failover, logging & task re-runs avoid data loss

What our customers have to say about us

What our customers have to say

“Although shortcuts would still work across the network after migrating to Microsoft 365, the prospect of maintaining a dedicated email archive on-prem was a non-starter. Essential worked out the best strategy for migrating our archived emails into Exchange Online.”

What our customers have to say

“We did our research into migration methods, including manual extraction, which was deemed totally impractical. We had no issues and no surprises and achieved our objective to complete our migration earlier than scheduled.”
