Hi @PRASHANT VYAS ,
I suggest you do some troubleshooting:
- What migration tool are you using?
- Does your migration process migrate the entire site including source and target lists or migrate lists one by one? If it is a one-by-one migration, it is recommended to try migrating the entire site including the source list and the target list.
- What did you do before this error occurred? It would be better if you could provide some screenshots.
Thanks,
Yanli Jiang
