Upgrade from 8.1 to 8.3: a few doubts

Hi,

I was studying the upgrade guide from 8.1 to 8.3 (I’m using 8.1.44) and I’d like to know if I’m understanding correctly a couple of points.

Point #1

In my setup I have and I use a Gateway Network (10 geteways connected): during the transition period, when I will have a mix of 8.1 and 8.3 gateways, I understand that I need to enable Allow Java Serialization in 8.3 gateways in order for the network to keep working…correct?

Point #2

The first block is clear: once the upgrade is completed, all the existing opc connections will go down and I will have to trust, for each one of them, the new certificates. That’s ok.

On the second block, instead, I have a doubt.
As of now, I have a bunch of opc connections configured like in the screenshot below, and Ignition needs to write into some of the tags available on these opc servers. Will keeping the configuration like this prevent Ignition from writing into tags because it won’t have write permissions? Is that what the guide is saying?

Thank you!
Andrea

If these are connections to third party servers, no, nothing will change.

If they are connections to another Ignition OPC UA server that has been upgraded to 8.3, yes, something will need to change.

What the guide is saying is that OPC UA clients that are connected to an Ignition OPC UA server with an anonymous user will not be allowed to write by default, but this can be changed in the permission settings of that server.

Yes
