Upgrade node red

Hello together,

I am actually working on a similar isue. I d like to upgrade node red because it offers now functionality with the MQTT nodes (dynamic subscription)

Now I am not sure from which path I have to start the upgrade, because I think there are two instances of node red on the IOT2050 controller with the example image 1.2.2. One in the root directory and one in the usr directory. I think the second instance will be startet by  the systemctl service.

Are the customized nodes preserved during the upgrade (node-red-node-intel-gpio-0.0.6-IOT2050)? That nodes are only available in the usr instance.

Can the upgrade also be done with the upgrade script for debian os, which is provided by nodered.org? I think that script does an upgrade on nodejs too.

Thanks for your help.

Best regards

Hi bergmanu,

thanks for your quick answer.

For my better understanding, if i d like to upgrade node red and node js on which directory (path) should I do this?

/root/...... or  /usr/lib/....

It is currently not entirely clear to me where node-red ist running on the IOT2050 when it is started via autostart (set in iot2050setup)?

Thanks for your help.

Best regards.​
