Question Installing Centos 7 over Centos 5, will my files and programs be available?


I've been having increasing trouble doing simple things on my EOL Centos 5 workstation. I think the solution is to install Centos 7 but I can't do that by upgrading. I believe I have to do a "new" install, and I have some concern that my current file structure may not be compatible. What can I do to make sure that files remain intact? Secondly, will it be possible to keep and continue to use programs that depend on Wine?

There's no perfect guarantee that your files will remain intact. That's why one makes and keeps backups of important data. That said, the risk of personal data loss can be considerably lower if your current installation keeps your personal data on a separate filesystem. Does /etc/fstab contain a line that includes /home? If yes, a new installation can reuse the filesystem that mounts to /home with minimal risk of loss. If not, you might wish to consider an upgrade installation to CentOS6, and later upgrade that to 7.

There is no upgrade from 5-6 except for a new install and read the upgrade tool from 6-7 is broken but not sure of its current status. A new install of CentOS 7 is really your only choice.

Without knowing anything about your current file system structure it is impossible to say whether it is compatible with version 7. As stated a backup of all your files would be best. It should be possible to continue to use Wine. While version 5 uses SySV init scripts, version 7 uses systemd and so they are completely different.

If needed there is a CentOS 7 32 bit version but do not know the status of its repositories or applications etc.

You can elect not to format your home partition in the anaconda installer for CentOS 7, but that assumes your home partition is actually a separate partition to your root partition. It's possible that if you've installed Wine in CentOS 5, and then install Wine (from software packages) in CentOS 7, then that could pose problems as far as the Wine configuration is concerned in your home folder.

I totally agree with michaelk, a clean install is the best way to install CentOS, if not the only way given what michaelk has said above.
