These platforms are absolutely free, and hence, some find it ideal to start their blog and then eventually move on to WordPRess.org or other paid platforms. The process of migration from one platform to the other requires exporting an XML file which contains all the posts that you have on your blog. If you blog has too many posts, naturally, the size of the exported XML file will be very large.

You can ask your web host increase the limit but in most cases, they will not as it is a universal limit. Therefore, the only way out is to split large XML files in WordPress. After splitting them into smaller files, you need to upload them one by one.
