Renaming Solr webapp in release 5.2.1

[saurabh tewari]

Hi,

Is there any way through which one can change the name of solr webapp? I
used to name my instances differently according to their usage and I'd like
to keep doing that, since I've mapped the solr APIs in my code using those
names only.

Changing solr.Date to solr.TrieDate

[saurabh tewari]

Hi,

I recently started to move my solr index from 4.8 to 5.2 via replication
from 4.8 master to 5.2 slave. I replaced all the primitive fieldtypes to
Trie-fields, since the original ones are removed from 5.2 . Replication
went successful, but when I fired a query on slave, it shows a class-cast
exception in solr.DateField.I understand that my documents are still using
old fieldtypes and my current schema doesn't support that. Is there any way
I can move my existing index to 5.2?
