[upgrade from premium to premium plus]

the real answer I am looking for is will I get more parcel capacity?  I am using 343 out of 351.  I don't want more land.. Just more land impact.  Will that increase so I can have more objects?  

[upgrade from premium to premium plus]

I already have a premium account with a beautiful Linden home but I am running out of space for my objects.  My land impact right now is 343 out of 351.  My question is, if I upgrade the the premium plus account, will I get more parcel capacity to put more objects?  and if I do, will that make me start over and have to pick a new home or will it not disrupt the home I already love and want to keep? 

[Upgrading my premium to premium plus]

I already have a premium account that is yearly paid in August and I already have a linden home that I love.   If I upgrade to the premium plus account, will the upgrade charge be prorated for the time I have left on my year that I already paid for?  Or should I wait until my renewal time in August to upgrade?  Also will upgrading to premium plus affect my linden home I have now?  I don't want to be suddenly kicked out of my linden home because I upgraded.  So, my question is will I be able to keep the linden home I have now?
