Shortcode migration

Hello,

Old web site contains old short codes. We migrated to Enfold and alot pages have old button shortcodes, button, according, like:

[button size=”small” src=”https://www……” target=”_blank” ] SOME INFO [/button]
and
[toggle_box]
[toggle_item title=”BIBLIOTEKININKYSTĖS IR KRAŠTOTYROS SKYRIUS”]
[/toggle_item]
[/toggle_box]
etc…

And we using Ultimate Shortocde plugin, and maybe you have ideal how replace Ultimete Plugins short codes to Enfold shortcodes too?

Any idea how add [button shortcode like [av_button…. ? or replace

Thank you
