Upgrade CENTOS 6 to CENTOS 7

[DesignerResource]

Hi,

I want backup my whole vps and re-install centos7 because the centos6 seem outdated now. Is it the snapshot from provider good to work with? I'm not do it before so I'm afraid I will need re-install everything from scratch :(.

Thank you for your support.

hi,
you can buy a same config vps and migrate data there (if you're using CWP there use cwp-cwp migration). If you don't want to change ip and stuff you can remigrate it from new to old server after removing centos 6 and installing centos 7.

I didn't rely on snapshots as it may contain old OS

@sandeep how are you? If I understand it well, I still need another vps for backup data and then migration it again, is it right? Are there any way not require vps and create a backup file then download the backup file and install centos 7 then install the backup file again?

P/S: I don't use CWP so it's out of my opinion.

in your case you need to take all mysql db backup and download your website files/script locally on your pc. Its not complicated things

but i didn't recommend you to use snapshot restore when you're upgrading from old os to new major versions.

Thank you so much, I will try to do it in the test server first then I will go with other vps later.
