Can not migrate cPanel backup but no errors shown

Hi all. I am currently migrating my cPanel account to Virtualmin. I created a full backup of my cPanel account (~23GB) and then migrated to Virtual by chosen options below:

I was waiting for a long time but when all things stop loading, there were no errors shown but the site (cPanel) was still not migrated. The disk usage was the same as before I clicked Migrate Now
Please help me to solve this
Thank you in advance!!!

P/s: my disk is 14.33 GiB used / 34.76 GiB free / 49.1 GiB total

Maybe it is due to big file size upload, I guess so…

I try uploading it directly to Virtualmin but it hangs at 16%

not very big by VS standards - if the import is ~23Gb it will likely need at least double that to unzip (that goes via tmp files). folk seem to think extracting zip/tar files has zero cost.

yes, I am trying to upload it by Upload and Download feature

was there not a file size limit for cpanel imports caused by some code rather than intention?

I am sure another user had this but I cannot remember if it was rectified.

makes no difference you still need the space to unzip probably > 46Gb and you have’t got that. it is likely to consume a big chunk of memory real+virtual

can you not break up the zip into smaller chunks?
