from my old layerslider enfold bundled version to uptodate layerslider plugin

Dear Enfold team,
I’ve just bought the last plugin version of the Layerslider (6.7.1).
I did “activated it”. But it did’nt “installed it” and I’m still with my 2016 Layerslider version

Here the issue message I got:
“Install Location: Non-standard Using LayerSlider from a non-standard install location or having a different directory name could lead issues in receiving and installing updates. Commonly, you see this issue when you’re using a theme-included version of LayerSlider. To fix this, please first search for an option to disable/unload the bundled version in your theme, then re-install a fresh copy downloaded from CodeCanyon. Your sliders and settings are stored in the database, re-installing the plugin will not harm them.”

In order to install it could you please validate what I am planning to?

– First whithin Enfold and specially my Enfold Child, I must deactivate the bundled version of the layerslider and keep safe my sliders and settings:

Within Enfold Child / Layout Builder / Integrated (Bundled) LayerSlider Plugin, I have 4 choices possibles:
1) Activate bundled plugin (actual choice)
2) Deactivate but leave plugin files in theme folder
3) Remove theme plugin files only and keep slides
4) Remove theme plugin files and slides

I hesitate between option 2 or 3. What’s best?
Thanks for your advice.

Otherwise, no problem to install Layerslider as an ordinary plugin.

Best regards.
Noemi
