plesk 7.5.1 -> 7.5.3 upgrade failure

[serg3263]

Situation:

1. First time failure occured when I run autoinstaller script due to MySQL incompatability.

I resolve this incompatability Problem: I found appropriate script named "mysqld" and put it into /etc/rc.d/init.d. At this point no MySQL compatibility errors.

2. Then I run manual update. At stage I running

rpm -Uvh psa-7.5.3-fc2.build75050506.13.i586.rpm

ERROR OCCURED:
==========================8<=================
Trying to add supplementary group 'psaserv' for user 'psaadm'... already there
group psacln already exists
/usr/local/psa/bin/chrootsh already registered as a login shell
Standard build detected. Upgrading canceled, because only
5.0.x versions supported for upgrading from Standard to RPM
builds.

error: %pre(psa-7.5.3-fc2.build75050506.13) scriptlet failed, exit status 1
error: install: %pre scriptlet failed (2), skipping psa-7.5.3-fc2.build75050506.13
======================8<=======================

IMHO aborted first installation process causes this error.
But

Q1:
What does mean next phrase:
---------------------------------------------------
Standard build detected. Upgrading canceled, because only
5.0.x versions supported for upgrading from Standard to RPM
builds.
----------------------------------------------------
?

Q2:
What package of version 5.0.x "is meanning " psa-....rpm?
