Hi ShivaniM,
The experimentation panel has not explicitly been mentioned for adobe campaign classic (ACC) like it has with adobe target or AJO. At least I haven't found anything that says so. But if the data is in the AEP then is should be possible to get it into this panel.
It is described as such:
"Create connection to experiment datasets:
The recommended data schema is for the experiment data to be in an Object array that contains the experiment and variant data in two separate dimensions. Both dimensions need to be in a single object array. If you have your experiment data in a single dimension (with experiment and variant data in a delimited string), you can use the substring setting in data views to split the dimension into two for use in the panel."
Depending on how the data has been ingested into Adobe Experience Platform, you can create a connection in Customer Journey Analytics to the experiment dataset. There is a description of this here: https://experienceleague.adobe.com/en/docs/analytics-platform/using/cja-workspace/panels/experimentation
