Proficy Historian: Implementation,
Upgrades, and Cloud
with Rain Engineering
Your plant collects data. Most of it disappears before anyone acts on it. Proficy Historian captures every alarm, every process event — permanently, securely, and in context.

Problems Your Proficy Historian Can Solve
These are the most common complaints manufacturers bring to Rain Engineering. We’ve fixed them all for manufacturers like you.
Data Nobody Can Use
Your Proficy Historian collects millions of points a day. But getting anything useful out takes hours of spreadsheet work. The data is there โ it’s just buried.
Tags Only One Person Understands
Cryptic names like “PMP3_T_OUT_B” made sense to whoever built the system in 2011. That person left. Rebuilding the context is expensive.
Disconnected from ERP and MES
Proficy Historian knows what equipment did. The ERP knows what was shipped. They never talk โ and management makes decisions on incomplete information.
Operations Hub Collecting Dust
It came with your Proficy license. Nobody’s ever turned it on. Dashboards, trending, and mobile access are sitting there unused.
Unpatched Security Risks
Proficy Historian servers sit at the IT/OT crossroads. Older versions carry known vulnerabilities. One audit finding costs far more than a planned upgrade.
Cloud Migration Feels Like a Cliff
Moving decades of process data to the cloud โ without losing continuity, managing sovereignty rules, reconfiguring remote collectors โ nobody wants to own that project.
Best-in-Class Industrial Time-Series Data Historian
Velotic Proficy Historian is best-in-class historian software that collects industrial time-series and Alarms & Events (A&E) data at very high speed, stores it efficiently and securely, and allows for fast retrieval and analysis โ driving greater business value across your enterprise.
With superior compression algorithms, Proficy Historian is approximately 30ร more efficient than relational databases and 2ร more efficient than leading competitors. Available for on-premises, hybrid, and cloud historian deployment on AWS or Azure, it scales from a single plant to enterprise-wide operations across hundreds of sites.
But the product is only the beginning. Most plants that struggle with Proficy Historian don’t have a software problem โ they have a configuration and strategy problem. That’s where historian implementation and support from Rain Engineering changes the outcome.
“No longer is there a default choice in historians. If GE Digital’s Proficy Historian [now owned by Velotic] is not on your short list, it certainly should be.”โ Joe Perino, Principal Analyst, LNS Research

Proficy Historian Services from Rain Engineering
There are plenty of Proficy resellers. There’s only one Velotic Proficy SI Platinum partner whose entire practice is built around getting manufacturing systems to actually work the way plants need them to.
Velotic Proficy SI Platinum
Rain Engineering holds the highest Velotic Proficy Solution Integrator tier โ direct product expertise, first access to new releases, and a vendor relationship that gets hard problems solved fast.
Product AuthorityShop Floor to Enterprise
Historian implementations fail when the integrator doesn’t understand what’s on the factory floor. Rain Engineering’s connectivity expertise spans PLCs, DCS, sensors, and every industrial protocol in between.
OT/IT ConnectivityTag Strategy First
Before configuring a single collector, Rain Engineering designs the tag naming convention and asset model that will make the system usable โ not just in month one, but in year ten.
Long-Term DesignEducation That Sticks
Training isn’t a checkbox at project close. Rain Engineering builds internal capability โ knowledge that stays inside the building when the engagement ends.
Skills Transfer2-Hour Support Response
When a historian goes dark or an integration breaks, every minute matters. Rain Engineering’s support SLA means expert help arrives before a minor issue becomes a production incident.
Ongoing PartnershipAI-Ready From Day One
ARC Advisory Group calls data quality the #1 barrier to scaling Industrial AI. A Rain Engineering historian implementation is designed to be the clean, contextualized foundation that makes AI actually work.
Future-ProofedThree Roles, One Clear Outcome
The people who benefit most from a well-implemented historian often feel its absence most painfully.
Something went wrong on Line 3 last Tuesday. I’ve spent two days trying to reconstruct what happened. The data should be there โ I just can’t get to it easily.
We have all this data and I still can’t see clearly how each line is performing, what’s trending wrong, or where we’re losing capacity. I’m managing on gut feel and weekly reports.
We’re on Historian version 7. There are security patches we haven’t applied. Now the business wants cloud analytics. I don’t know where to start and I can’t afford downtime.
AtriCure: What Real Outcomes Look Like
AtriCure is a fast-growing medical device company producing cardiac surgery tools across 30 production and assembly work centers. Like many manufacturers, they were managing scheduling and data with Excel โ and the complexity was becoming unmanageable during double-digit growth.
Rain Engineering analyzed their situation, selected and deployed the right tools, and integrated them with their existing ERP. The results arrived faster than expected โ and kept improving as the business grew.
Systems are complicated. You don’t have to figure it all out alone. Results were better than anticipated.
Recognized by Velotic as a Platinum Solution Partner
Rain Engineering is widely recognized as a top Proficy MES integrator under both the GE Vernova and Velotic partner programs. Our close relationship with the Velotic product team gives clients direct access to the latest Proficy Historian innovations โ including the 2025 Kafka, Data Hub, and cloud scalability enhancements โ before they become widely available.

Common Questions About Proficy Historian โ Answered
Proficy Historian is best-in-class historian software from Velotic (formerly GE Vernova) that collects industrial time-series and A&E data at very high speed, stores it efficiently and securely in the cloud or on-prem, and allows for fast retrieval and analysis. Rain Engineering specializes in Proficy Historian implementation, upgrades, and ongoing support for manufacturers across North America.
A cloud historian stores industrial time-series data in a cloud environment rather than (or alongside) an on-premises server. Proficy Historian for Cloud runs in your own VPC on AWS, supports 1 billion samples per minute, and reduces manufacturing software costs by up to 30%. Rain Engineering designs and deploys cloud historian architectures โ including migration from on-prem installations โ for manufacturers ready to move OT data to the cloud.
Proficy Historian is extremely capable, but it requires proper tag naming conventions, asset model design, device connectivity, and integration with MES and ERP to deliver its full value. Without a specialist, most plants end up with cryptic tag names, siloed data, and dormant Operations Hub licenses. Rain Engineering’s historian implementation services get the configuration right from day one โ including tag strategy, asset modeling, and Ops Hub activation.
Proficy Historian uses a time-series architecture optimized for high-frequency industrial data โ it’s approximately 30ร more efficient than relational databases. Standard databases are built for transactional data (ERP records, orders) not the millions of values per second generated by plant floor sensors and PLCs. The difference matters especially for long-term OT data storage: a relational database storing 10 years of plant data would be prohibitively large; Historian compresses it to a fraction of that size while keeping retrieval fast.
Yes. Rain Engineering designs and executes Proficy Historian cloud migrations to AWS, including VPC setup, data migration, API continuity validation, security hardening, and Ops Hub activation. We handle the full lifecycle so your team doesn’t need to learn cloud infrastructure from scratch โ and your existing applications continue working without reintegration effort.
Proficy software was originally developed by GE Digital, then moved to GE Vernova’s industrial software portfolio. In 2026, GE Vernova rebranded its industrial software business as Velotic, bringing Proficy, Kepware, and ThingWorx together under one unified brand. Rain Engineering is a Platinum partner under both the GE Vernova and Velotic programs and maintains an active collaboration with the Velotic product team on Proficy Historian development.
