Joomla site migration

PLEASE BID ONLY IF YOU KNOW JOOMLA 6. I already have a Joomla site built on an old version on Joomla. I need to create the similar site on Joomla 6 using Casseopeia theme. No new theme is required. The original site has several article and pages but your goal is to : recreate the homepage and basic layout, color scheme, menu, module positions, and a few dummy articles to make the menu work. Data migration from old site to new is not needed. Images you can copy from source site if needed. You can enter dummy text. I will login and enter real text later. -------- More Details ------ >Do you already have the Joomla 6 install ready? Yes. I will provide admin userid and pwd. >and should the rebuild stay fully inside Cassiopeia overrides only? Yes. >Which menu items and module positions from the old site must be matched first? Top bar with contact info, logo, menu bar, slide show of products, contact info on bottom, and a few menus at bottom. Will provide exact details in chat but it is a simple site. Not many menus and modules. >The main job is to recreate the front page and the basic structure on Joomla 6 without touching content migration. That means rebuilding the template styling, menu behavior, module placement, and a few dummy articles so the navigation works cleanly. Correct. Similar look is required. Exact look is not required. Slight variation is fine. >A key challenge is matching the old look while staying compatible with Cassiopeia. The safest way is to inspect the old site, map its layout into Joomla 6 module positions, then adjust template settings and CSS overrides instead of forcing changes into core files. Right. Use minimal overrides. >Are there any custom extensions or modifications on your current Joomla site that need to be migrated? There are a few old custom extension but nothing critical. Something similar can be used on the new site. Exact look is not necessary. > What version of Joomla is the website currently running on? 3 point something
