svn dont show the status of files

Good Day,
    I've updated the Subversion at the working stations from 1.2.x to
1.4.x, but the server, that is running FreeBSD, still with the 1.2.x
version. The problem is with the working copies at the local machines.
Every time a single file is modified, the all folder is set with the
"unknow" status, and this why the client dont know what to commit. By
the way we are using the eSVN client. I've notice that are two files in
".svn": format and entrys. The valeu of format is 4 in 1.2.x version and
at the 1.4.x is set to 8. The entry file is complitely diferent between
the 1.2.x and the 1.4.x version. I depend on a answer to get this
upgrade done.
Regards
