Citrix to Azure Virtual Desktop — remote workforce rebuild

Multi-office business, 80 staff · Financial & professional services

Remote staff struggled with Citrix performance and VPN instability. Citrix renewal quote forced a decision — migrate to AVD or pay premium prices for another three years of pain.

The problem

Daily desktop issues, slow logons, and helpdesk tickets eating IT capacity. Citrix licensing renewal was 40% higher than expected. No documented DR for virtual desktop environment.

Constraints

  • Users in Brisbane, Sydney, and remote — latency sensitive
  • Compliance requirements for session logging and access control
  • Must complete before Citrix renewal deadline

Approach

  1. Step 1

    Pilot

    Built AVD host pool in Azure, migrated 15-user pilot group, benchmarked performance vs Citrix baseline.

  2. Step 2

    Identity & security

    Entra ID conditional access, MFA enforcement, M365 security baseline, session policies aligned to compliance needs.

  3. Step 3

    Wave migration

    Department-by-department cutover over six weeks. Parallel run for two weeks per wave, then Citrix decommission.

Deliverables

  • Azure Virtual Desktop environment — production
  • M365 security hardening
  • User migration and training materials
  • Runbooks for provisioning and troubleshooting

Results

Logon time
Reduced average session start by ~60%
Helpdesk tickets
