i've LR 3.6 and I want to buy LR6. is necessary to buy full version or there is an upgrade version? IS necessary to convert the catalogue from LR 3.6? thanks
Go to Products, scroll down to Lightroom, click the arrow next to I want to buy (Full), and choose Upgrade.
LR6 will upgrade a copy of your LR3 catalog, this normally happens automatically when you launch LR6 the first time.
Note that Lightroom catalogs are not backwards compatible, so the LR6 catalog can not be opened by LR3.
