Hello. I own server which runs FreeBSD 4.x-STABLE (last updated 27 March 2006). I want to update it to 6.x-STABLE. I known, that update via sources is not recommended in my situation, so I want to do clear installation. The problem is the following: there is many ports installed, many Internet sites hosted on old system and so on. It will take a lot of time to configure new system to do all things, which old system was doing. But I don't want that services do be not accessible for a long time. I want to try the following trick: 1. Install FreeBSD 6.x-STABLE on the separate HDD, while it is inside my home PC. 2. Place this HDD into server, make it bootable. 3. Boot new system, and mount old HDD (with FreeBSD 4.x and all old stuff) 4. Setup jail inside new system, which will run old system. 5. Now I have all services running, and I can transfer it to new system one by one quietly. I believe, that FreeBSD is backward compatible, and all my stuff, which successfully run on 4.x sill run inside jail on 6.x. I am right? Did anybody tried to do something like this? What was the results? -- Best regards Mikhail Vladimirov <vladimirow@mail.ru> P.S. I already have jail inside my current installation of 4.x. So I actually plan to setup two jails inside new 6.x. One for original system and another for my current jailed system, which also run several useful services.
