Upgrade Path

Upgrade path refers to the versions you need to install to get from your existing version of Plant SCADA (or Citect SCADA) to the latest version of Plant SCADA.

Some versions included substantial changes to the product, which require incremental upgrades involving intermediate steps between versions. The number of necessary steps will depend on whether you do an offline or online upgrade (see Upgrade Method).

• For an offline upgrade, you can upgrade a project directly from any version of Citect SCADA from 5.21 onwards.

• For an online upgrade, you can go directly from the following versions:

  • Plant SCADA 2023

  • Plant SCADA 2023 R2.

    If you would like to perform an online upgrade from an earlier version, you will firstly need to temporarily upgrade your system to one of the versions listed above. For more information, see the Installation Guide for the intermediate version.

    You can download the installers for earlier versions from the Products page of the AVEVA Knowledge & Support Center (located at https://softwaresupport.aveva.com/).

For both offline and online scenarios you need to:

• Apply the latest update to the version you are upgrading from.

• Perform the upgrade to Plant SCADA 2026.

• Apply the latest updates to Plant SCADA 2026.
