Historian Migration

Migrate your historianwithout losing the history.

A historian migration is not simply moving time-series data. Tags, timestamps, metadata, asset structures, interfaces, calculations and downstream applications all have to move together.

The Migration Process

A controlled path fromdiscovery to cutover.

Every environment is different, but the migration process needs to be structured, measurable and reversible.

01

Discover

Inventory historians, interfaces, tags, assets, dependencies, data sources and operational requirements.

02

Assess

Evaluate architecture, data quality, capacity, performance, compatibility and migration risks.

03

Design

Define the target historian architecture, infrastructure, interfaces, security model and migration approach.

04

Migrate

Execute historical data migration, metadata mapping, interface deployment and parallel validation.

05

Validate

Verify timestamps, values, mappings, asset structures, calculations, interfaces and application dependencies.

What Must Be Considered

The historian is onlyone part of the system.

Successful migration requires attention to the wider environment surrounding the historian — from data and metadata through interfaces, applications and operational continuity.
