migrate a 1.5 site to the current release Joomla 3.9

[Csapó Krisztina‎]

Hi Joomlers, I am about to migrate a 1.5 site to the current release. Anyone did something like this recently? I know the documentation on Joomla.org, I am interested in your personal experiences with the official path or any other tip or hint you may have. I did this before, but it was years ago :S This is a very low budget project for a non-profit, so I'd rather use free solutions wherever I can (Akeeba Backup Pro is available)
