Backup restore from XWiki Enterprise 8.2.1 to 11.9 results 404

maharshi.vyas · February 19, 2020, 4:33pm

Dear Team,

I installed fresh instance of xwiki 11.9 on Ubuntu 18.04 using apt (apt-get install xwiki-tomcat8-mysql), which works.

Then I am trying to restore backup from 8.2.1 instance (mysql database restore, permanent directory, WEB-INF) which results in 404 error for me.
I get following error in my /var/log/tomcat8/catalina.2020-02-19.log

Not sure what I am doing wrong. Could you please help?
Thanks,

What do you mean exactly ? The entire WEB-INF folder ?

maharshi.vyas · February 19, 2020, 4:38pm

Yes

tmortagne · February 19, 2020, 4:44pm

The WEB-INF folder is not data, it actually contain most of the XWiki logic. So you now have a mix of XWiki 11.9 and XWiki 8.2.1 (but mostly 8.2.1).

When you use the Debian package the configuration files are located in /etc/xwiki/ that’s the files you need to merge (and not replace) instead of WEB-INF.

Why 11.9 by the way ? The current LTS (and highly recommended) is 11.10.3.

tmortagne · February 19, 2020, 4:46pm

Would have been safer to install XWiki 8.2.1 on your new server, restore the data/configuration and only when you are sure it’s working as the previous instance do the upgrade.

maharshi.vyas · February 19, 2020, 4:49pm

I mean I copied the following file

WEB-INF/xwiki.cfg (old XWiki configuration file but still used)
WEB-INF/xwiki.properties (new XWiki Configuration file)
WEB-INF/classes/logback.xml (Logging configuration)
WEB-INF/observation/* (Cluster configuration)

I should not? Or in the xwiki backup/restore docs it’s mentioned just to backup to be on a safer side?

11.9 because I have a test instance where I installed xwiki with this version and got a snapshot of it. So I just have to rollback and try again rather than installing again and again for clean setup.

Is it possible to install 8.2.1 via apt?

tmortagne · February 19, 2020, 4:53pm

maharshi.vyas:

I mean I copied the following file

WEB-INF/xwiki.cfg (old XWiki configuration file but still used)
WEB-INF/xwiki.properties (new XWiki Configuration file)
WEB-INF/classes/logback.xml (Logging configuration)
WEB-INF/observation/* (Cluster configuration)

OK so not the entire WEB-INF folder then

The configuration files should be merged (i.e. reapply your customization to the new files) and not overwritten.

Is it possible to install 8.2.1 via apt?

Yes. The package name is just different (xwiki-enterprise-* instead of xwiki-*) but it will be replaced and upgraded when you install xwiki-* 11.9.

Among other things one good thing about doing it like this is that dpkg will take care of the merging of the configuration files for you (or tell you if there is a conflict).

maharshi.vyas · February 19, 2020, 4:54pm

I see. Thanks for the help. I will try as you suggested and revert back.

Best Regards,

maharshi.vyas · February 20, 2020, 5:29pm

Hi,

I will try as @tmortagne suggested very soon. But I managed to get the wiki up with backup restore.
The thing is now I see all the pages in xwiki but no content, I get -

$renderedContent

But when I try to edit the page, I can see the content.

maharshi.vyas · February 26, 2020, 5:42pm

Hi @tmortagne,

I followed you steps and could restore the backup to 8.2.1 Xwiki instance.

After that I updated the xwiki package to 11.10.3 version.

The wiki is up but I still get the “$renderedContent” when I visit my wiki pages.

Could you please help?

Also until I restored the data to my new 8.2.1 instance on 18.04, everything worked fine. I can not login as any LDAP user as well

maharshi.vyas · February 27, 2020, 10:55am

Also I when I click on the notification icon I get

Failed to execute the [velocity] macro. Cause: [DefaultNotificationFilterPreference is not mapped]. Click on this message for details.

amadis · February 27, 2020, 12:42pm

@maharshi.vyas you may export necessary pages from your old version (by global administrator → Global Administration → Content → Export), then install new fresh version, make sure it working fine and import xar into new working version. Hope this solve your issue

maharshi.vyas · February 27, 2020, 1:32pm

@amadis But according to wiki backup restore doc XWiki Export feature not recommended. Also we have multiple wikis in there.

I do not know what I am doing wrong, I reverted back to working 8.2.1 state and did an upgrade via apt and now I have HTTP Status 404 – Not Found Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

sorry to bother you but any idea about this? @tmortagne

tmortagne · March 3, 2020, 8:40am

Your issue seems to be with the Markdown extension 1.1 (which use Parboiled to actually parse the content). Looks like it did not like the upgrade but the error does not give much information on the why. You should make sure you have the very last version of it.

vmassol · March 3, 2020, 9:22am

Please make sure to use the Markdown 1.2 extension: https://extensions.xwiki.org/xwiki/bin/view/Extension/Markdown%20Syntax%201.2

It’s the only recommended one.
