Thanks for posting the Query.
When you will install Lightroom 6 , you can open your catalog in Lightroom 6 and that will get upgraded, it actually creates an upgraded copy of the Lightroom 5 catalog.
All your presets will be transferred as both Lightroom versions of have the same location of presets.
All your photos will be linked as the information stays within the catalog.
Not sure about the plugins, we may need to re-install that.
As you already own Lightroom 5, I would recommend you to buy Lightroom 6 upgrades only directly from Adobe : Adobe Store - Adobe Lightroom 6 - Upgrade
Thank You for the answering my questions, much appreciated. I clicked on the link you provided & its to Adobe in India, I don't understand the currency on the site page, clicked US under different countries tab & it took me some place else entirely. I don't know if it's me or what but Adobe gets confusing to use sometimes. I will do the upgrade through Adobe just need to find the right page. Thanks Again.....Jerry

Here is the link to buy CS6 products.
Please choose upgrade from the drop down menu of that product version : http://www.adobe.com/products/catalog/cs6._sl_id-contentfilter_sl_catalog_sl_software_sl_c reativesuite6.html
Thanks for your reply. Sorry for not responding sooner, I've been dealing with a crisis that has taken over our family. Starting to even out a bit, keeping my fingers crossed. Again many thanks for the info....Jerry
