请教个yum升级的问题

最近打算将fc6升级到fc9，
一直出现如下的错误：
Error: Unable to satisfy dependencies
Error: Package kdenetwork needs libcrypto.so.6, this is not available.
Error: Package mkinitrd needs nash = 5.1.19.0.3-1, this is not available.
Error: Package kdesdk needs perl(DCOP), this is not available.

Error: Package gnome-panel needs libedataserver-1.2.so.7, this is not available.
Error: Package mkinitrd needs libparted-1.8.so.2, this is not available.

我搞不清这些动态库去哪里找？所以删掉了一些包，剩下这几个不知道
卸载会不会出问题。请各位指点。

升级跨的版本太多了，还是重新安装吧。
