Replicate a Vision Project in Perspective While Keeping OPC-DA Connection Working?

Hello!,

I’m currently replicating an existing Vision project in Perspective, and the system uses a local OPC-DA connection (via COM).
Since OPC-DA only works on the same machine as the Gateway, I want to avoid using tunneling tools and keep things simple.

My questions:

  • Can I run both the old Vision project and the new Perspective project in the same Gateway to share the existing OPC-DA connection and tags?
  • Is it safe to just install both the Vision and Perspective modules on the same Gateway?
    • The current Gateway is already running Vision — I would need to install a newer version to support Perspective.
  • Can Perspective use the same OPC tags without any reconfiguration?
  • Are there any best practices for working with both projects side-by-side during migration?
  • Alternatively, would it be possible to run two Gateways on the same machine (one for Vision, one for Perspective) and still access the local OPC-DA server from both?
    (I have valid licenses for both.)

Thanks in advance for your help!

  • Yes
  • Yes
  • Yes
  • Nothing in particular
  • Maybe? (I wouldn't. Just have one connection to the DA server.)

Ok, my step by step plan would be:

-Install new ignition gateway on another port in same server as the Vision project so Vision project keep runing and don´t bother current users.

-Move all configuration from older gateway to new one.

-Move current perspective project.

-Keep both projects running in different gateways...or is better just move the vision project also?

Thanks!

I would say just do your in place upgrade and add the perspective module. The clients will need to relaunch, but other than that, it will be non intrusive. You can then make a separate project for perspective to work on it. If you haven't set up inheritance now would be a good time to do so and move all users to an inherited project off of a parent. Then both vision and perspective can inherit off of the parent.

Thanks @michael.flagler

Good to know the new gateway is compatible with Vision projects.

The restart of operator clients is complicated? What they would need to do? Is something I would need to do from the gateway or they only do from their own devices?

I didn´t set up the first Vision project.

They'll restart on their own, but ideally you'll want to go back afterward and upgrade all the client launchers to the latest version also. If this is a v7 to v8 upgrade, then I don't know if they'll even relaunch on their own though, so you may be having to install the new client launcher first before doing the upgrade.
