subversion 1.4.2

[Eric Manceau]

Hello,

I am struggling with an old version of subversion : 1.4.2
Is it safe for the repository to adopt the 1.6.16 version?
Moreover I want to split an old repos in 2 new repos without losing 
revision of my files :

Old Repo
   |--data
   |-- test

New Repo 1
   | --data

New Repo 2
   | --data

Svndumpfilter with 1.4 did not help and the svn command as well so did 
the tools evolve in the 1.6 version in order to achieve this goal?

Thank you for your answer.

Best regards,
E. MANCEAU
