Hello  , 

this is my first post for DSPACE .

I am trying to Moving items ( 5000) from diffent collections under diffent 
communites to under one community and diffent collections ?? what is the best 
method to do this ?

i treid these two SQL scripts but now getting error for  reindex

update item
set owning_collection=NewCollectionID
where item_id=ItemID;

update collection2item 
set collection_id=new collection it
where collection_id= old collection;


once it run these two scripts  i can see total number of items by title under 
new collections 

but can't see them under new community .

i tried to update this table communities2item  , then its showing total number 
of items under community as well as differnt collections but 
when i am trying to reindexing  getting this error message 

./dspace index-update
