Solr cloud upgrade from 5 to 6

Hi Guys,

I would need a piece of advise about upgrading solr cloud.  Would I need to
re-index data If upgrade Solr cloud from 5.5.4 to 6.6.2?

Thanks in advance.

No, Solr works hard to guarantee compatibility
one major revision back so any 6x version should
be able to work fine with any 5x version.

A couple of free bits of advice, worth what you pay
for them:

1> don't just use your configs from 5x in 6x. Rather
start with the stock 6x configs and customize them
as you did for 5x.

2> Really look over the CHANGES.txt, particularly hte
upgrade section for all versions between 5.5.4 and
6.6.2.

3> If you _can_ reindex, I always do if for no other reason
than that'll force me to look at what's new and make use
of it. Again you don't _have_ to though.

Best,
Erick
