I want to store AVERAGE data with a 5 minute interval for two years. I have a few thousand existing rrf's which have the wrong RRA, which makes them store the MAX data with a 5 minute interval for two years.
My question is this: If I use the resize.pl tool from this page: http://docs.cacti.net/manual:087:8_rrdtool.4_resize is the only thing I need to change the number of rows for the following, already existing RRA: ?
You need to change that RRA, yes. But you should resize all consolidation functions for the same consolidation level. In other words, resize all RRAs using 600 data points. There's an appropriate feature in my script

Thanks for this! I managed to resize my RRDs correctly. One problem now remains: As soon as I zoom in in my graphs they are empty. But the data is there, I checked it by dumping the data. And the graphs which are not zoomed do show lines. Any suggestion what could have gone wrong?
Nothing went wrong. Only you have to wait until the new data slots are filled by consolidating data as it comes in
Perhaps I should mention that in the docs ...

But the the data collected every 30 minutes is still there .. Does that mean that when I don't zoom, it doesn't take information from the 5 minute data slots, but when I zoom it takes that data (which is empty) ?
Yes. RRDTool chooses a "best consolidation level match". Unfortunately, after a resize it does not check whether data is already filled into that consolidation level
