I have a server which i will upgrade and i want to migrate it to my new server. My old server and new server both plesk 10.x installed. there are 54 clients and 90 site with 50Gb totally. But it could not migrate and just writing failed without any error. I also try to download all backups but it could not succed from the download link on the panel because it always waiting an answer from plesk panel for long long hours. I try to download from sftp but it also could not succedd because some of sites' backup files are larger then 5 Gb so any of the os. is not accepting this much huge file. I decide that this could be succedd to download other small peaces and setup this huge sites manually again but without the backup of huge sites plesk telling me this backup should not work because there is an error. I think it is talking about missing parts that i should not download to new machine show me a way to migrate please.
