is it possible to stage 2 versions of IOS-XE Everest in eve-ng?

We already have numerous CSR's deployed running csr1000vng-universalk9.16.05.02.Everest, but we need to test a feature in csr1000v-universalk9.16.06.06 (also Everest)... is it possible to use the instructions from your how-to:

to just load this new version? Would be able to pick from the 'add node' dropdown? Would both images be able to run in parallel without issues?

Thanks!

Use the same how just prepare new image..
under one csr can be numerous images..

thank you for the answer... one follow-up question - is it possible to change between IOS versions if we have 2 versions available for 1 device? For example, switching between 16.06.05.Everest & 16.06.06.Everest? The GUI allows you to stop the node & edit the boot image, but the node seems to ignore this when booting & only boots to the image you added the node with...

thanks again!

yes, but you mate did not read our how to..

Once node is started (CSR), EVE created tmp hdd for it... and image is running on it.
even you will change images for this node after stopping, it still will boot from saved tmp hdd. (previous image xe ios, because it is saved)
so how to:

run your CSR node, save cfg (wr) and EXPORT it !!!
then wipe node (this will clean(DELETE) your tmp previous hdd
set node boot from exported
change image(new XE IOS) from which you want start node
Start node, it will boot from exported cfg which you made from previous xe version.
DONE

And please pay some time to read our cookbook, this algorithm was explained very well.
