There are a few ways to move data i will list them in the order that i pref to do it myself

1) Download FlashFXP ( you can get a 30 day test for free ) then load up both your old and new seedbox and drag and drop the files you want to copy, I would go to /seedit4me/torrents/rtorrent and then do Ctrl A to select all and drop in to the same folder on the new server ( if you get any fails you just right click and click reset all failed) this is by far the quickest way you can also turn off rutorrent on your new slot and copy over your .seesions folder and then turn rutorrent back on and it will reload all your active torrents 

If using Ver 5.4.0 or higher you might need to change one setting so it does not use your home upload speed 

Site Manager , Transfer , Site to Site method, and make sure it is on Direct (FXP)

2) Resilio Sync your find this on your dash under app's install it on both seedboxes, Then go to your current box and open the app 

1. Click Create Identity i just leave it as seedit4me

2. Top Left click the + sign 

3. Click standard folder and point it to where your data is ie /home/seedit4me/torrents/rrorrent and click open

4. Click Key and copy the key

5. With the key you just copied go yto your new seedbox open the app and do step 1 and 2 again

6.Click Enter Key and paste the key you copied there and then point it to where you want the data to go ie  /home/seedit4me/torrents/rrorrent  

thats it leave it to move the data for you
