[1.6.6 nightly] DB Upgrade script changes vs 1.6.5

[NOB]

Hi

The new DB upgrade script to migrate from 1.4 to 1.6 adds the last
2 of the recommended indexes and a few more. Fine.

However, there is another change to the graphs_items table
where the length of the color field is changed from varchar(32)
to varchar(6) and the content is changed, too.

What happens to the distributed monioring if one server is updated
now (using varchar(32)) and a new one is installed (with varchar(6)) and
connected later to the first one ?

Will there be any problems ?
What about servers already upgraded using the script included in 1.6.5 ?
Is it required to apply the latest changes on those, too ?

Questions over questions.

I'm curiously waiting for the answers.

Regards

Norbert.

Added: The reason for the change is ZBX-213 (bug report)

[NOB]

Hi

even if there is no consequence: i would like to know it for sure
instead of risking that our ZABBIX environment will go down
after the upgrade from 1.4 to 1.6.6 on some, to 1.6.5 on other
servers.
