Thanks Freshman. Apologies for being a NXT newbie. I've already transferred my NXT amount to my MyNext.info web wallet for safe-keeping. However, the Ardor credits I've acculmulated is stranded in my old wallet. Is it possible to transfer that to the web wallet before 12th October?
I don't know how to upgrade either and couldn't find anything about it on the NXT website. That's my dilemma!
You can't move Ardor credits before October 12th, they'll be unfrozen on that date together with the hard fork, after which you can only use 1.10.1+ to make transfers.
So you might have to upgrade from 1.9.2 anyway. If you're on windows, you should be able to just download and click .exe file and it'll install/update everything.
https://nxtforum.org/nrs-releases/nrs-v1-10-2/Don't be afraid to delete anything accidentally. Nxt doesn't have wallet files stored on the computer, you must remember your passphrase, that's all. Don't forget the passphrase though.
If something goes wrong with the upgrade, simply delete all folders related to Nxt which you can find using windows search facility and install 1.10.2 again from scratch. You'll be able to use in instantly in the Roaming Client mode, see your balance and make transfers, while blockchain is slowly downloading in the background.
UPGRADE SUCCESSFUL! Thanks!
For NXT newbies like myself I'm giving a map of how I did it below. I hope this isn't going to be too long-winded.
HOW TO UPGRADE A NXT DESKTOP WALLET
Here are the steps I took (from memory):
1) I went to the 1.10.2 website
https://nxtforum.org/nrs-releases/nrs-v1-10-2/ and downloaded the SHA-512 flavour of 1.10.2. I chose SHA-512 because it runs faster on 64-bit machines, like the one I have. If you have a 32-bit machine it would seem that the SHA-256 .exe file would be the one for you.
2) The 1.10.2 .zip file was downloaded to a folder on my desktop. I unzipped into that folder, but I couldn't see an obvious .exe file. I then copied the .zip file, and unzipped and pasted it directly to my desktop. Again, I couldn't see any obvious way forward.
3) I opened my wallet to fully download the blockchain before going any further with the installation. When the blockckchain was downloaded I noticed something different. The NRS version number at the top right was activated as a roll-over hyperlink.
4) I clicked on the hyperlink highlighting "NRS 1.9.2
Outdated!"
5) A box opened up signposting me to update by clicking on the message.
6) After clicking a browser window opened up and I located the
installation button for 1.10.2 by navigating to it on my desktop and clicked on it. I hadn't noticed it before. Within a few seconds my wallet confirmed that the 1.10.2 download was correct and had the right hash.
7) Nothing more happened, so I closed the wallet and clicked on the installation button for 1.10.2. It told me that there were existing files on my computer (from my old installation) and did I want to overwrite them. I said YES.
NRS version 1.10.2 was installed automatically.
9) I opened my wallet using the new NXT server icon and put in my wallet ID in the box provided.
10) When my wallet opened I was pleased to see that it had been updated. No waiting. In the top right hand corner it said "NRS version 1.10.2" and the outdated warning had disappeared. All my Ardor credits were intact. I had earlier transferred my NXT over to an online MyNxt.info online wallet for safe-keeping.
As mentioned before, the steps are from memory so bear that in mind, but I think they are a reasonably accurate log of what I did. Maybe someone could come along, polish and add to my crude efforts and put it on the opening page to guide other NXT newbies on upgrading their wallets.
I had originally accessed my wallet using the NXT server icon to open it. As a test I opened another desktop wallet I have (with nothing in it) using the wallet icon. It too had updated, so I am very pleased and thankful for the help others have generously given me.
It must be noted that wallet version 1.9.2 and lower must be updated to 1.10.2 before 12th October
