Hi ZhangHuangbin, we haven't written to each other for more than 13 years... and I can say that for these years I am extremely satisfied with iRedMail. The server I am trying to migrate has an Uptime of 2433 days, 5 hours, 21 minutes!

I have two mailservers installed that I want to migrate to the latest version, I think it's time for them to migrate to the latest version.

The server I am trying to migrate is iRedMail v0.9.5-1 with iRedAdmin v0.6.1 (LDAP), Cent OS 3.10.0-327.18.2.el7.x86_64.

I installed Debian 12, and iRedMail-1.7.1, exported from the old server the LDAP database following the instructions, downloaded updateLDAPValues_095_1_to_096.py and updateLDAPValues_099_to_1.py, set
basedn = 'o=domains,dc=example,dc=com'
bind_dn = 'cn=vmailadmin,dc=example,dc=com'
bind_pw = 'passwd'
and when running the script it gives the following error:
root@mail-new:/home/dimi# python3 updateLDAPValues_095_1_to_096.py
File "/home/dimi/updateLDAPValues_095_1_to_096.py", line 20
print "* Connecting to LDAP server: %s" % uri
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print(...)?

I'm obviously going to need some help, thanks in advance!
