"CMSImport, every Umbraco content migrators best friend"
Today we've released version 3.3.1 of CMSImport. We've fixed a couple of issues and if you are using Umbraco 7.4 Beta it's a must install since it fixes an error in Member import related to Umbraco 7.4 and it allows you to use the decimal datatype.
Besides this we've added a separate MySql provider that allows you to use MySql as a datasource. It's not added to the core package of CMSImport because only a handful of people will use this provider.
PM> Install-Package CMSImport.DataProviders.MySql
Using the provider works the same as the SQL server provider. Specify a connection string, and specify a query.
