Upgrading the DHTMLX suite to latest version

Hi Team,

We are currently on dhtmlxSuite v.5.1.0 (Professional edition) and we would like to migrate to the latest version of dhtmlxSuite (Professional edition).

There are a few concerns before we take up this upgrade and we need your assistance for clarification. Below are the details:

  1. We have given a few customized scripts while purchasing the dhtmlxSuite v.5.1.0 (Professional edition). Will those scripts (screenshot attached) work with the latest version?

  2. We are looking for a migration guide to upgrade from 5.X to 8.3.X version like the following. - Migration to Newer Versions DHTMLX Docs

  3. We are heavily dependent on DHX Grids and Trees so we would like to know if there are any API-level changes that break the functionality.

Best Regards,
B Akshay Kumar Reddy.

Unfortunately since v6.0 update the dhtmlxSuite API has completely changed. There is no possibility to use any method or custom function from the dhtmlxSuite 5 in the later version of the dhtmlxSuite.
The only solution is to completely rebuild an app.
