OPC Classic is an older technology widely adopted for industrial automation and control systems. OPC UA (Unified Architecture) is the successor to OPC Classic and offers several advantages. OPC UA is more interoperable, flexible, and secure than OPC Classic. It also supports new features such as real-time data, information modeling, and event-based communication and has a more modern architecture.
To migrate from OPC Classic to OPC UA, a number of steps must be taken. First, it is essential to comprehend the current OPC Classic system and how the organization uses it. This includes understanding the current data models, communication protocols, and hardware and software platforms.
Next, an OPC UA migration strategy should be developed. This plan should include an evaluation of the current system, identification of the OPC UA components that will be required, and an implementation schedule. Also included may be pilot testing of the new system and employee training on the new technology.
Once the plan is in place, the migration process can begin. This may involve installing new hardware and software, configuring the OPC UA system, and ensuring its functionality through testing. The OPC Classic system can now be retired and replaced with the OPC UA system.
It is important to note that the migration process can be complex and time-consuming; therefore, it is recommended to collaborate with experts in the field to ensure a seamless transition.
Why should you move from OPC Classic to OPC UA:
There are numerous advantages to migrating from OPC Classic to OPC UA (Unified Architecture) for your industrial communication systems. Here are a few reasons you may wish to migrate to OPC UA:
OPC UA’s built-in security measures, such as encryption and authentication, safeguard your system against unwanted access and cyber threats.
OPC UA can handle many devices and more data than OPC Classic, making it appropriate for large-scale systems and Internet of Things deployments.

Future-proofing: OPC UA is the most recent version of the OPC standard and will likely be the predominant standard for many industrial systems. Migration to OPC UA can assist in ensuring that your systems are compatible with emerging technologies and standards.
Better data access and management: OPC UA offers a more advanced data model that enables more efficient data access and administration, enhancing your systems’ functionality and performance.
Remote Access: OPC UA offers remote access to devices, data, and system control, which can be advantageous for remote monitoring, maintenance, and troubleshooting.
Noting that switching to OPC UA is a difficult process that requires careful planning and execution is essential. It is advised to have a specialized team in charge of the migration, along with a clear plan and budget. Furthermore, testing and monitoring are essential to guarantee that the migration goes smoothly and that the system is functioning properly.
Step-by-Step Guide to Migrating from OPC Classic to OPC UA:
OPC Classic and OPC UA (Unified Architecture) are both industrial communication protocols. However, OPC UA (Unified Architecture) is more contemporary and advanced. If you are still utilizing OPC Classic, consider switching to OPC UA to take advantage of its numerous advantages. Here is a step-by-step tutorial to assist you in making the change:
Step 1: Assess your present OPC Classic environment. Determine whether systems and applications are utilizing OPC Classic and which data they are transferring. This will assist you in identifying any potential migration issues.
Step 2: Create a migration strategy. Create a thorough plan outlining the steps to transition from OPC Classic to OPC UA. This strategy should contain dates, necessary resources, and any contingencies.
Step 3: Perform a migration test. Before migrating your complete system to OPC UA, you should test the transition on a modest scale. This will assist you in identifying problems and making any necessary improvements.
Step 4: Train your employees. Ensure that all personnel who will interact with OPC UA have received the appropriate training. They should be conversant with the standard’s new features and capabilities, as well as how to troubleshoot any potential problems.
Step 5: Upgrading your hardware and software is the fifth step. Ensure that all your gear and applications are OPC UA compatible. This may necessitate the upgrade of certain hardware and software.
Step 6: Implement the migration in Step 6. Once testing and training have been completed, the migration can be implemented on a bigger scale, and this should be done in phases to avoid operational disturbances.
Step 7 is to observe and maintain. After the transfer is complete, observe your OPC UA environment thoroughly to ensure everything is functioning as planned. Adjust as appropriate and maintain employee training on the new standard.
It is essential to remember that OPC UA migration is a complex procedure involving numerous components and systems. It is optimal to have a specialized team in charge of the relocation, together with a detailed plan and budget. In addition, testing and monitoring are essential to guarantee a seamless migration and a well-functioning system.
