Large scale history migration into AspenTech IP21

There is not much we have not come across in upgrading, installing and migrating data from legacy systems into more modern real-time historians. History migrations can be time-consuming and process intensive so it is important to get it right first time. High frequency data collection over a number of years across daylight savings boundaries can add to the complexity and magnitude of the operation if you are not prepared. A clear understanding of where you are moving data from and a well designed and understood end goal is a key step in the planning stages. When high volumes of data are involved it makes it more important to make sure that the migration is as slick as it can be and the need for reworking the data is negated. Do it once and do it correctly the first time.

On this project we were combining data from 3 separate VMS systems and a legacy Windows historian into a single AspenTech Infoplus.21. Custom tools were developed in order to run the data migration in as efficient as possible a manner making the best use of time out of office hours.

As always this project had a tight deadline and the work had to be completed in a maintenance window. It was a high pressure project that was successfully completed before the scheduled plant startup.
