Password encryption - migration user accounts from SuSe to RedHat

Hello guys,
I'm currently working on replacing old server and it's migration from SuSe

Code:
SUSE Linux Enterprise Server 10 (x86_64)
VERSION = 10
PATCHLEVEL = 4

to the RedHat
Code:
Red Hat Enterprise Linux Server release 6.4 (Santiago)

Problem seems be in migration of users passwords, respectively in password encryption.

On SuSe is used des encryption
Code:
cat /etc/default/passwd | grep CRYPT
CRYPT=des

but in /etc/shadow I see:
Code:
user1:$1$gDXlJQcH$1Z5otL/07nPZJtF8VVaGY0:15552:1:93:7:::
user2:$2a$04$Osw2KnOXMJjDvYuvtoJAked1cnjXBF3RRpJhqmi21.C1nQrQ89jNi:15580::::::

So it looks that some from passwords are encrypted with MD5, and some of them with Blowfish. Is my suggestion right??

While RedHat is using SHA512
Code:
cat /etc/login.defs | grep CRYP
ENCRYPT_METHOD SHA512
MD5_CRYPT_ENAB no

I would like ask if is possible to convert current passwords from MD5 and Blowfish to the SHA512 and use them directly on new RedHat server??


Many thanks for hints.

For the LIST DIRECTIVE, REMOTE and/or CODE can be empty: LIST "" "" - list all configured remote names LIST REMOTE "" - list all codes of REMOTE LIST REMOTE CODE - list only CODE of REMOTE The SIMULATE command only works if it has been explicitly enabled in lircd. -h --help display usage summary -v --version display version -d --device use given lircd socket [/var/run/lirc/lircd] -a --address=host[:port] connect to lircd at this address -# --count=n send command n times EXAMPLES
