Hi,

I have a production instance of licode installed from commit 34e6653, now I see lots of commits in master branch.

How can I update my instance? Do you have process to update?

My worry is about losing data or if I need to make some manual actions to ensure the service.

Thanks

I’m trying to perform the update in a snapshot of my production environment, but I’m having issues.

I’ve executed [installUbuntuDeps.sh](http://installUbuntuDeps.sh) because I’ve seen in commits you have changed the node installation to use nvm, but when I try tu start all node precess the nuve process gives me the next error:

```
/usr/share/licode/nuve/nuveAPI/mdb/erizoControllerRegistry.js:11
    db.erizoControllers.find({}).toArray(function (err, erizoControllers) {
                        ^
TypeError: Cannot call method 'find' of undefined
    at Object.exports.getErizoControllers (/usr/share/licode/nuve/nuveAPI/mdb/erizoControllerRegistry.js:11:25)
    at checkKA (/usr/share/licode/nuve/nuveAPI/cloudHandler.js:90:29)
    at wrapper [as _onTimeout] (timers.js:261:14)
    at Timer.listOnTimeout [as ontimeout] (timers.js:112:15)

```

Then I’ve executed [installNuve.sh](http://installNuve.sh), but the problem persists and after this script execution the SuperService ID and SuperService Key have changed.

Do you have any doc describing the update process? Is a way to update without changing SuperService credentials?

Yes thanks,

Now it runs correctly.

But the update process is still make me headache, after I run the installErizo and installNuve I can see that the licode\_conf.js has been replaced by the fresh one and I lose all my config.

Do you have the process or steps to update licode and don’t lose information or config?

I’m back with new problem after solving the erizoController.  
Now I have problems with erizoAgent, I can see this in the erizoAgent log:

Searching in google I’ve found this post [http://stackoverflow.com/questions/22868307/undefined-symbol-in-node-js-c-addon-under-linux-why](http://stackoverflow.com/questions/22868307/undefined-symbol-in-node-js-c-addon-under-linux-why) and I’ve tried to debug

```
/usr/share/licode/erizoAPI/build/Release(master*) # nm -C addon.node|grep node_module_register root@dagobah-licode
                 U node_module_register
------------------------------------------------------------

```

The node\_module\_register appears as undefined, is this related to bad script execution? how can I re-launch the scritps to solve it?

Thanks

Have you built erizo after the update?
