Be aware that if it is an unpatched version of 5.0.77, then there is
a bug related to name_const (http://bugs.mysql.com/bug.php?id=42014)
that can cause serious problems (infinite server crashes if it
happens in a replication thread). Redhat/CentOS have applied the
patch, but other sources might still have that bug.

Depending on the "seriousness" of your environment you can read the
changelogs and upgrade if you don't see any showstoppers. I have
hardly ever seen any problems with minor version upgrades of mysql.
Of course what Rob says is true, and it is a good idea to test things
out in a test environment first. But I know many environment where it
is "okay" to just run the upgrade, as long as it is a minor version
upgrade. I guess it depends on the type of production environment you
are running in.
be careful though!

Hello everyone,
i am quite new to mysql and i recently begin to work with a company
who is using mysql 5.0.45 in production.
i think this version is too old and would like to upgrade to the
most
recent 5.0.xx
my os is CentOS release 5.3.
is it safe to simply use "yum upgrade mysql" ?
are there any important differences i should be aware of between
5.0.45 and 5.0.77 ?
any diffferences in password encoding etc. ?
the db is properly backed up and replicated on two 5.0.77 slaves.
thank you
Marco
I would not simply upgrade. I would upgrade the test environment
first
and have the development team sign off that there were no bad effects
caused by the upgrade.
The first version of 5.0 that I think is particularly useable and not
buggy is 5.0.67. I suggest that this is worth the upgrade.
In theory there are not significant differences between 5.0 versions
after GA other that bug fixes. I *do not* trust this.
