V3.5 Dump file Loading failed in Aura DB

I have been trying to upload the dump file onto Aura DB instance , but it doesn't load successfully. After couple of minutes, the loading process gets failed. However my dump file size is lower than 4 GB. It just around 3.50 MB.
What could be the solution for it?

More than likely the failure is as a result of trying to import a 3.5 dump into a Aura DB running v5x and this is not supported
