Migration from SugarCRM 6.5.18 to SuiteCRM 7.8.1 - issues with the Classic Theme

We are about to migrate from SugarCRM 6.5.18 which has a number of customisations build with the Module Builder and a few additonl fields added through Studio.

When I run a test of the migration to SuiteCRM 7.8.1 everything seems to work ok, however the Classic Theme has some major problems around the search and filtering of fields. We have over 120 users of the system and moving upgrading to one of the other themes is not practical in the short term.

There are errors in the display of the accounts list view.

I Tried disabling the filter using the options for the config override php file. but that did not help and only covers the 3 modules not all modules in the system.

We are running on windows server 2008, Apache 2.4.7 and php 5.5.6

When I add an entry enable legacy filter for a module the old search forms show but the advanced option to change the fields listed in the list view still stays as in the image below. This view is even there for the Quick filter as well. And dos not allow you to see any of the other information required to change the fiedls in the list view. I chose the Cases module to show this as there have not been any changes to this module through Studio

have you been able to resolve? we’re doing the same, migrating from sugarcrm to suite, but the suitecrm theme is unuseable.

we want something as similar to classic sugar as possible.
