Literacy: DEDECMS Dream Content Management System, is the most well-known PHP open source Web site management system, webmaster Network Admin5 that is the use of the program built.

Previously based on Dede 5.1 make a station http://www.seafoodl.com

A number of custom models have been used, and some programs have been modified, and if you jump to 5.3, you risk the following uncertainties:

1. The official upgrade procedure does not guarantee the complete migration of the custom model data;

2, label, template engine replacement;

3, the site structure changes, the upgrade after the collection of search engine problems.

I to 5.3 in the initial installation of the machine, feel a greater improvement, operation details and experience and speed sense of ascension, teeth decided to upgrade.

Of course, the first is to use a copy of the local debugging upgrade, not recommended directly on the server.

The upgrade process went well and there was no hint of error.

The program is completely 5.3, just keep 5.1 of the database, the impression that 5.3 should be 78 tables, upgraded into 111, these are not mentioned, do not affect the overall situation.

Debugging after the upgrade is still very difficult.

1. About Custom Model Data migration

The migration process is smooth, but there are still some flaws, some of the field values will be lost error, it is only to do their own to modify the database.

2, Template update

Almost all of the templates were done again, but it was just a bit of a comb.

3, the structure of the site changes

The general structure has not changed, at least the generated data page address has not changed, but to pay attention to a number of small details, such as tag page, map page changes, make some corresponding processing, not to repeat.

Summary: In the local debugging finished, has now officially switched to a new version, for 5.3 I feel very good, 5.1 of the advantages of it all have, of course, there are some habits of change, need you to move some brain, Dede is very good!

You are welcome to join the discussion on this issue during the upgrade process. Also hope that you point out Dalian Seafood Daquan website deficiencies, thank you.
