Hi, migration from cloud to server is easier than from server to cloud - so good for you. Documentation how to do this is here: https://confluence.atlassian.com/adminjiracloud/migrating-from-jira-cloud-to-server-776636236.html

Yep, 2008 R2 is not supported. https://confluence.atlassian.com/adminjiraserver/supported-platforms-938846830.html

Can you share which versions of apps are showing here in administration? /plugins/servlet/applications/versions-licenses

Then you should try to contact Atlassian directly by https://support.atlassian.com/contact/#/

Did you read his post from beginning or not? Git has beeen upgraded using ppa:git-core/ppa to 2.21 and now Bitbucket Server doesn't start anymore. I've removed git and the source and then installed the latest available version of git on Ubuntu 16.04LTS: And his question on end of post? How can I obtain such a git version…

Yes, 2.20.0+ is supported, but not 2.21.0+ in date of this problem. Important is second dot in version number. So simple - if application support specific version which is not as latest in repo then I need to use steps to install specific version. Thats all ... nothing else

But Bitbucket doesn't support latest versions of Git. :-) That's a reason why @Oliver Stock got that error.

That's not solution if application doesn't support latest version as I mention in my answer - and that was exactly this problem. .

Hi, do you mean functionality of issue collector? https://confluence.atlassian.com/adminjiraserver071/using-the-issue-collector-802592637.html

Hi, you can't simply switch to another custom field plugin without need of migration or losing data. Usually reason for moving from free to paid is simple - more features, active development. BTW especially this plugin is really cheap for bundled features.

Hi, can you share your log where are error lines (INSTALL-DIR/logs/catalina.out)? Also try to delete cache as suggested by @sara https://answers.seibert-media.com/t/how-to-delete-clear-the-plugins-cache-in-jira-server/54

Hi, it looks like someone restrict your permissions for Space. Did you check this with your admin? 

Hi, can you share log file (HOME/logs/atlassian-confluence.log) from same time when this problem occur?

Hi, yes, you should update plugins every time when you make upgrade of application. I don't think categorization is something wrong if you are simply upgrading everytime. ;-)

Hi, there is option for logged-in user as you can check links in linked answer, but how do you want get info about membership when user is not logged-in?

Hi, I could recommend to you look at those documentation pages. https://confluence.atlassian.com/doc/space-permissions-overview-139521.html https://confluence.atlassian.com/doc/page-restrictions-139414.html You can set many variants of permission configurations based on your use case and what do you need. Your "folders"…

Hi, MariaDB is not supported, you need to use normal MySQL https://confluence.atlassian.com/adminjiraserver/supported-platforms-938846830.html

Hi, if you already have DB as CMDB you can use nFeed plugin (https://marketplace.atlassian.com/apps/23337/elements-connect-formerly-nfeed?hosting=datacenter&tab=overview) Or if you don't have CMDB or if you want have it all in Jira then you can use Insight as CMDB in Jira…

Hi, just follow this article: https://confluence.atlassian.com/confkb/how-to-fix-the-collation-of-a-postgres-confluence-database-966676071.html 

Not exactly Redmine but another tools yes. Jira has many app/service specified importers so I there could not be any problem.

Hi, then disable AD by following this via SQL https://confluence.atlassian.com/jirakb/administrator-cannot-login-after-reordering-user-directories-235669137.html And use any of local users to check AD configuration (if you don't know who is admin or password follow this…

Hi, you can find some useful info here https://confluence.atlassian.com/adminjiraserver/importing-data-from-redmine-938847599.html

Hi, no, it's not. For that user is user.

If you are Jira admin then share part of log when you are trying to log in.

Hi, because it's your instance you need to contact your administrators of Jira and maybe also AD admins if they didn't change something recently.

Can you share your server.xml (in code block)? There could be some misconfiguration I think. 

Hi, what is output of command below? netstat -pantu | grep 8090 Based on error line with Caused by: java.net.BindException: Address already in use it looks like something another is using port and/or IP? 

Hi, can you share part of log when you try to start and stop application? It looks like problem with escaping space in path.

Hi, can you try to click on enable and share part of your log since that action?

Hi, supported platforms for Jira 8.1 find here: https://confluence.atlassian.com/adminjiraserver/supported-platforms-938846830.html
