[xwiki-users] Issues while importing previous working xwiki XAR file in to new installed XWIKI setup?

Hi all, I have xwiki setup done on machine A with custom setting like log changed, user, group and space rights settings .Also had space contents/attachment. Now i did the fresh installation of xwiki on new machine B..What i wanted was every setting,content, attachment i created on machine A xwiki database should be migrated to machine B xwiki database. ** *What i did for this is :-* 1) On machine A, as admin user navigated to export. It asked me package name and description. I entered the value in that and it created a A.xar file. 2)Now after xwiki installation i.e after extracting * xwiki-enterprise-web-3.3.war* inside tomcat on machine B, i navigated to import and imported A.xar file.Now i log in as admin user. *Actual Problem* Now i see the main space webhome page on machine B different from machine A main space webhome page.Like under space i see this error Unknown macro: spaces The "spaces" macro is not in the list of registered macros. Verify the spelling or contact your administrator. Same error is there for Tags.Also i do not the setting i did on default colour theme like i changed the logo. Though i can see all the previous user,group ,space rights and content. *Not getting what i am missing here?*
