- Prije nadogradnje na <em>squeeze</em>, potrebno je izvršiti
- prijelaz sa PHP inačice 4 na PHP 5. Ukoliko je na
- sustavu još uvijek instaliran PHP 4 pojavit će se
- poruka:
-
-<example>
-+-----------------------------------------------------------------+
-| Nadogradnja CARNet Debian Lenny->Squeeze |
-+-----------------------------------------------------------------+
-| |
-| Prije prelaska na Debian Squeeze potrebno je napraviti |
-| nadogradnju sa PHP 4 na PHP 5. |
-| |
-| Pokrenite: |
-| # apt-get update |
-| # apt-get install php5-cn |
-| |
-| Nakon sto provjerite da sve web aplikacije rade ispravno, |
-| ponovno pozovite ovu skriptu. |
-| |
-+-----------------------------------------------------------------+
-| < U redu > |
-+-----------------------------------------------------------------+
-</example>
-
- Lokalne izmjene u PHP 4 konfiguraciji treba ručno prenijeti
- u PHP 5 konfiguraciju. Također je potrebno instalirati PHP 5 inačice
- dodataka koji se koriste u web aplikacijama
- (npr. <package>php5-mysql</package>, <package>php5-ldap</package>).
- </p>
-
<p>
U sljedećem koraku biti će izvršena provjera dali su najvažniji
servisi nadograđeni na najnovije inačice u <em>lenny</em>
