Very basic question that I can't find a simple answer to.... What day will access to Salesforce Classic (NPSP) no longer be available? I understand that with recent release we can switch profiles back and forth. With Winter '20 (out in Oct. 2019) will access to Classic be completely gone the day that goes into Production? Or is that rolling? Or will you be able to stay on Classic forever but Salesforce will no longer support? I know they want us to move to Lightning -- but my org needs to understand the exact time frame as this is resources we have to gather to make this change. Thanks for any insight.
