The forgotten archive: what happens during mergers, acquisitions and organisational change?
Historic email archives are often overlooked during mergers, acquisitions and organisational change programmes. This article explores the risks of fragmented archive platforms, inconsistent retention policies and vendor lock-in, and explains why archive migration should form part of every cloud modernisation and integration strategy.
Why IT teams underestimate email archive complexity
Legacy email archive migration projects are often underestimated because the real complexity lies beneath the surface. From PST sprawl and journal archives to metadata integrity, retention conflicts and vendor lock-in, historic email environments contain years of accumulated technical and governance challenges that organisations frequently don’t discover until migration planning begins.
What happens to archived email when staff leave?
When staff leave, their archived email often remains behind in legacy systems with unclear ownership, inconsistent retention and outdated access controls. Migrating legacy archives into Microsoft 365 or Google Workspace helps organisations strengthen governance, reduce risk and improve eDiscovery.
How to build a business case for decommissioning your legacy archive
Many organisations continue to run legacy email archive platforms long after moving to Microsoft 365 or Google Workspace, creating unnecessary cost, operational overhead and compliance complexity. This article explores how to build a clear business case for decommissioning legacy archives by assessing licensing, infrastructure, eDiscovery, governance and long-term cloud strategy — helping organisations understand why maintaining ageing archive systems is often more expensive than retiring them.
Email security modernisation creates archive lock-in — unless you plan for exit
Modern email security platforms often bundle archiving, retention and continuity features into their services, creating hidden long-term dependency on a single vendor. This article explores how archive lock-in develops during email security modernisation projects, why it creates operational and compliance challenges, and how organisations can retain flexibility by treating historic email data as a portable asset that can be migrated independently into Microsoft 365, Google Workspace or other modern archive environments.
The truth about journal archives – and how to retire them safely
Journal archives were once central to email compliance strategies, but many organisations now find themselves maintaining costly legacy systems that duplicate the capabilities of Microsoft 365 and Google Workspace. This article explores the risks of retaining outdated journal archives, including fragmented eDiscovery, inconsistent retention and increased operational overhead, and explains how organisations can safely retire them while preserving compliance, auditability and historic email data integrity.
Planning a multi-phase email archive migration: lessons from a large NHS organisation
Large-scale email archive migration projects require careful planning, phased delivery and strong governance to minimise risk and disruption. Drawing on lessons from a major NHS organisation, this article explores how a structured multi-phase migration approach helped manage complex archive environments, improve eDiscovery and compliance, and support the safe transition of historic email data into Microsoft 365 while maintaining continuity for critical services.
From on-prem to cloud: why archive migrations are nothing like mailbox migrations
Mailbox migrations and archive migrations may sound similar, but they involve very different challenges. While mailbox migrations typically focus on active user data and continuity, archive migrations must address historic data quality, retention policies, metadata integrity, compliance requirements and long-term eDiscovery needs. This article explores why archive migration requires a different strategy, specialist tooling and a stronger focus on governance when moving historic email data into Microsoft 365 or Google Workspace.
How to audit a legacy email archive in one week
Auditing a legacy email archive doesn’t have to take months. This article outlines a practical one-week framework for assessing archive platforms, data quality, retention policies, security controls and eDiscovery capability — helping organisations understand migration readiness, identify compliance risks and plan a smoother transition to Microsoft 365 or Google Workspace.
The 10 biggest data-quality issues found during archive migrations (and how to solve them)
Data quality is one of the biggest factors affecting the success of an email archive migration. This article explores ten of the most common issues organisations encounter — including duplicate data, orphaned mailboxes, corrupt PST files, inconsistent retention policies and broken indexing — and explains how identifying and resolving these problems early helps reduce migration risk, improve compliance and ensure a smoother transition to Microsoft 365 or Google Workspace.
