====== Migrate ======

Migrate Linux from X to Y.

===== Rename user =====

First of all, login with ''root'' , then using ''usermod'' to change username:

<code bash>
usermod -l newUserName -d /home/newUserName -m oldUserName
</code>

> Linux use uid to identify user, so changing username will not affect permissions.

Then, find all broken symlinks and fix it:

<code bash>
find . -xtype l
</code>

Last but not least, Search all configurations and change username, I recommand [[https://github.com/BurntSushi/ripgrep|ripgrep]].

<code>
rg oldUserName
</code>
