UPGRADE IN OJS 2.4.8 FOR OJS 3.0.0 error

Dear,
I’m
having the following problems after updating the OJS
php
upgrade.php check

Code Version: 3.0.0.0

Database version:
2.4.8.0

Latest version: 2.4.8.1

Database version is older
than version code

Run “upgrade.php upgrade” to update
And
while trying to update the database it gives me the error:
[Pre-install]

[Load:
upgrade.xml]

[Version: 3.0.0.0]

[Code: Installer Installer
:: syncSeriesAssocType]

[Date: dbscripts / xml / upgrade /
2.4.0_preupdate_usageStatistics.xml (skipped)]

[Date: dbscripts
/ xml / upgrade / 2.4.0_preupdate_usageStatistics2.xml]

ERROR:
failed Upgrade: DB: Table ‘issue_galleys_stats_migration’ already
exists
Besides
this my page is totally unrecognizable.
The
page is No Formatting

Could help? Thank you.
I
decided doing the following:

Moved to another place the
public_html directory where was all the unzipped base OJS 2.4.8 and
efetuei extraction OJS3.0.0 with a new public_html folder to the same
place.
So
I could install the wheel by http. Instead of creating a new database
by the panel, only filled the database information that already
existed with the OJS version 2.4.8. My question now is:
Is there any future problem with doing this?
Are there differences between the bases of OJS3.0.0 and OJS2.4.8? Where can I read about?
What is the correct way to do?

Thank you.
