The “src_” prefix is added to some migrated product attributes and all migrated attribute sets when you do not select “Clear current data on Target Store before migration.”
Because your Target Store may already contain attributes or attribute sets with the same names, the prefix helps distinguish the newly migrated data and prevent naming conflicts. For example, an attribute set named Clothing on your Source Store may appear as src_Clothing after migration.
If needed, you can remove or change the prefix in Magento Admin by going to Stores > Attributes > Attribute Set and editing the migrated attribute set.
At this point, you can either leave out the “src_” prefix or change it into any name you want. Changes can be made in any attribute set.
Please note that Magento’s Default attribute set does not receive the “src_” prefix.
