Assume we have an installed Linux system on hand. We have six parts to transfer: (1) User accounts; (2) User files (/home); (3) Database; (4) Apache; (5) PHP; and (6) crontab.
<h2>User accounts</h2>
Copy and transfer the following user-related files and directories:

<xmp>．/etc/passwd - File - contains various pieces of information for each user account
．/etc/shadow - File - contains the encrypted password (and aging) information for user's accounts.
．/etc/group - File - defines the groups to which users belong
．/etc/gshadow - group shadow file (contains the encrypted password for group)
．/var/spool/mail - Generally user emails are stored here.
．/home - All Users data is stored here.</xmp>

Do remember to "preserve (-p)" file info (permisions, owner, etc) in the transfer. <b>Do not copy-and-paste the passwd/shadow files directly.</b> It's recommended to only attach the human-added users into the new system user account files.

<h2>User Files (/home)</h2>
(1) rsync
Transfer a certain user folder:<pre>rsync -av /home/user/ account@domain:/home/user/</pre>
Or

(2) Tar
cd /
tar -cvpf /archive_folter/home-YYYYMMDD.tar home --exclude=home/exclude_foler

Untar:
cd /destination_folder
tar -xvpf home-YYYYMMDD.tar

<h2>Database (PostgreSQL)</h2>
Backup (export):
Shell> pg_dumpall -U postgres | bzip2 > cluster_YYYYMMDD.bz2

Transfer (scp) and unzip (bzip2 -d) the database cluster file.

Restore (import):
Shell> psql -f cluster_YYYYMMDD -U postgres postgres

Config:
shared_buffers = 2GB (1/4 of the memory is a reasonable starting value)

Assume we have an installed Linux system on hand. We have six parts to transfer: (1) User accounts; (2) User files (/home); (3) Database; (4) Apache; (5) PHP; and (6) crontab.
<h2>User accounts</h2>
Copy and transfer the following user-related files and directories:

<xmp>．/etc/passwd - File - contains various pieces of information for each user account
．/etc/shadow - File - contains the encrypted password (and aging) information for user's accounts.
．/etc/group - File - defines the groups to which users belong
．/etc/gshadow - group shadow file (contains the encrypted password for group)
．/var/spool/mail - Generally user emails are stored here.
．/home - All Users data is stored here.</xmp>

Do remember to "preserve (-p)" file info (permisions, owner, etc) in the transfer. <b>Do not copy-and-paste the passwd/shadow files directly.</b> It's recommended to only attach the human-added users into the new system user account files.
