How can I merge 1.5.3 and 1.7.1 into 2.5.8 ? - Joomla! Forum - community, help and support

hello.
i know there's lot of info on how upgrade 1.5 2.5 but, none of stuff i've read answer question have.

first of all; have 2 websites 1 on 1.5.23 , other on 1.7.1. merge both websites one. don't know best solution this. thinking of creating new website on date j! version: 2.5.8 , copy or upgrade 1.5.23 2.5.8 , 1.7.1 2.5.8.

both of these sites have on 700 articles each , don't want loose content.

now, after doing upgrades; links previous article work?

would better upgrade 1.5.23 1.7.1?

can please guide me best practice possible...

i need articles , categories , sections.

thanks in advanced time , help.

my suggestion be:

• create backups of sites using akeeba https://www.akeebabackup.com/compatibility.html
• transfer sites localhost (xampp localhost http://www.apachefriends.org ).
• after transferring sites localhost
• set standard template default 1.5.3 , update 1.5.26 don't worry updating extensions not going use site after export data.
  (suggest use 1.5.26 full package , use files except /installation folder)
• use http://extensions.joomla.org/extensions ... port/12816 export articles , users of 1.. when select section exports associated categories , articles , creates sections/categories categories/sub categories.
• set standard template default 1.7.1 , update 2.5.8 http://docs.joomla.org/upgrading_from_j ... joomla_2.5
• when have got site updated/upgraded 2.5.8 , checked update extensions(some update via extension manager update ... others not)
• then import data(previously exported 1.5.26) 2.5.8 http://extensions.joomla.org/extensions ... tion/15807

then site , transfer hosting server.
