What is the "cached" database?

[alchan]

i was disable database cache on store, before i use copy of this database for instalation

[alchan]

store cache ..

[Dmitry_Fedyuk]

Where did you read what using a "copy of this database for instalation" is a correct installation procedure?

[alchan]

i want to upgrade store with new package. I work in different folder on same server.

For instructions i look:

http://www.customerparadigm.com/magento-development/upgrade/how-to-upgrade-magento/

and

http://neoshops.de/2013/08/03/how-to-upgrade-magento-using-old-database/

do you have any suggestion?

For upgrading Magento 2, I recommend to use the manual from the official Magento 2 documentation, not legacy third-party articles for Magento 1.x.
