Extjs6 backward compatibility with sencha touch

[Zak7]

I am new sencha touch. Since sencha released Extjs6 so I want to ask whether Extj6 is backward compatible with sencha touch 2

[Gary Schlosberg]

I wouldn't say that there is backward compatibility, but Ext JS 6 has two toolkits, classic and modern. The modern toolkit is based on Sencha Touch, so upgrading from Touch to the modern toolkit can be straightforward depending, of course, on your application.

Thanks for the quick reply.
