we are going to upgrade our typo3-instance from version 6.1.5 to 7.6. Since we need to clone the instance and afterwards upgrade it in two steps (6.1.5 -> 6.2, 6.2 -> 7.6) we wonder if it was easier to setup a clean 7.6 instance and migrate the data (templates, sites, binaries etc.) afterwards.
There are multiple instruction pages on the web describing how to upgrade to 6.2 and to 7.6 but it seems to be a really tricky process.
So I'd like to know if the t3d data is compatible between those versions. Can we export the data from 6.1.5 and import it to 7.6 without troubles?
What do you think of the approach?
