Migration from Debian x86 to x64

Is it possible to move all ISPConfig (config + linux groups/users + mysql + files) from my 32-bit Debian (x86) to 64-bit Debian (x64) ?

I have 2 partitions: /var and "others"

Thanks in advance

 

But what about user and groups accounts? What should I copy from old 32-bit system disk to the new one with installed 64-bit system? I understand I should install also all ISPConfig3 stuff, duplicate database, copy /var/www/ and? What should I do for example with virtual hosts files?

 

VirtualHost files can be found in /etc/apache2

 

I've got problems with moving data from /etc/group

Source server:

Code:

vmail:x:5000:
getmail:x:5001:
sshusers:x:5002:web1,web2,web5,web6,web7
ispconfig:x:5003:www-data
client1:x:5004:www-data
client2:x:5005:www-data
client4:x:5006:www-data
ispapps:x:5007:www-data
client5:x:5008:www-data
client3:x:5009:www-data

Destination server:

Code:

vmail:x:5000:
getmail:x:5001:
sshusers:x:5002:
ispapps:x:5003:www-data
ispconfig:x:5004:www-data

After merging:

Code:

As I understand this numbers (group ID) are important and I shouldn't manually reorganize this fields?

What should I do now?

How filesystem works? Will my filesystem/owning system crash if I manually change this IDs in groups file?

 

bump, anybody can help?

 

bump......

 

Ok, I found out on the net that there is no sense in doing such a thing because I should also manually chown /var/www/... files.

To close.
