Import nintex user defined action
In case we need to move nintex workflows using user defined actions between environments, they must keep the same User Defined Action guid. We have to use only UDA export in .uda file, not .nwf file. Following Id node value must be present in workflow .nwf file
<UserDefinedActionDefinition><Name>Task
Reminder User Defined
Action</Name><Id>22f40f51-5a61-44f5-9e67-c9d1d707a151</Id>
