Upgrading database

[kalastaja]

I did remove zc_install (1.5.4) as said, but now I realize that I need it for upgrading the database. Is there anything but the zc_install folder (that I might have removed) that I need to include?

[kalastaja]

Do I first upgrade the db and then "upgrade" (copy/overwrite/...) the code, as the new code requires the new database!?

All you need is the zc_install folder. Run it and follow the instructions for Database Upgrade.

Would it even be possible to upgrade only the db "right now" and then upgrade the code a little bit later - just a bit longer transition period!? It would simplify the transition chaos for me.

Both the installed files and database versions (of Zen Cart) need to match to ensure proper functioning.

I would recommend against just "overwriting files" and instead recommend following the sage advice posted in the FAQs for "rebuilding" on the new version - starting with a copy of the old database and completely clean Zen Cart 1.5.4 files.

It may sound daunting and complicated at first, but in my experience this process (rebuilding the files and upgrading the database) is the fastest and most stable way to perform an upgrade (and allows one to better evaluate necessary plugins and theme changes in the process).

OK, thanks!

upgrading from 1.5.3 to 1.5.4. When I first logged into to my admin it told me to delete the zc_install folder. Now I get the message Your database appears to need patching to a higher level. See Tools->Server Information to review patch levels. How do I do that? I see posts about upgrading from older versions.
